Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528522, here are decompositions:

23 + 31528499 = 31528522
71 + 31528451 = 31528522
89 + 31528433 = 31528522
149 + 31528373 = 31528522
173 + 31528349 = 31528522
239 + 31528283 = 31528522
281 + 31528241 = 31528522
293 + 31528229 = 31528522

Showing the first eight; more decompositions exist.

IPv4 address
