%N A352233 Numbers that can be expressed as the sum of two primes in exactly 10 ways.
%C A352233 All terms are even. Conjecture: 632 is the last term. Hardy and Littlewood conjectured a growth rate of the number of decompositions for large even numbers (see Conjecture A in page 32 of Hardy and Littlewood reference), implying this sequence is finite. - _Chai Wah Wu_, Mar 10 2022
