Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529974, here are decompositions:

5 + 31529969 = 31529974
41 + 31529933 = 31529974
83 + 31529891 = 31529974
131 + 31529843 = 31529974
191 + 31529783 = 31529974
257 + 31529717 = 31529974
293 + 31529681 = 31529974
467 + 31529507 = 31529974

Showing the first eight; more decompositions exist.

IPv4 address
