Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541596, here are decompositions:

5 + 31541591 = 31541596
89 + 31541507 = 31541596
113 + 31541483 = 31541596
167 + 31541429 = 31541596
179 + 31541417 = 31541596
197 + 31541399 = 31541596
353 + 31541243 = 31541596
467 + 31541129 = 31541596

Showing the first eight; more decompositions exist.

IPv4 address
