Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533698, here are decompositions:

37 + 31533661 = 31533698
61 + 31533637 = 31533698
67 + 31533631 = 31533698
127 + 31533571 = 31533698
151 + 31533547 = 31533698
181 + 31533517 = 31533698
199 + 31533499 = 31533698
439 + 31533259 = 31533698

Showing the first eight; more decompositions exist.

IPv4 address
