Conjecture: a(n) > 0 for n > 4. - Sean A. Irvine, Nov 23 2021

			a(6)=18 since 6th prime is 13 and 31-13=18. a(9)=1980 because 9th prime is 23 and the smallest prime in P(6) different from 23 is 2003; 2003-23=1980.
a(23)=(8*10^31+3)-83 because 8*10^31+3 is closest prime distinct from 83 but in P(83). - _Sean A. Irvine_, Nov 23 2021
