Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535722, here are decompositions:

5 + 31535717 = 31535722
41 + 31535681 = 31535722
83 + 31535639 = 31535722
89 + 31535633 = 31535722
131 + 31535591 = 31535722
173 + 31535549 = 31535722
293 + 31535429 = 31535722
311 + 31535411 = 31535722

Showing the first eight; more decompositions exist.

IPv4 address
