Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529846, here are decompositions:

3 + 31529843 = 31529846
97 + 31529749 = 31529846
223 + 31529623 = 31529846
307 + 31529539 = 31529846
367 + 31529479 = 31529846
433 + 31529413 = 31529846
487 + 31529359 = 31529846
499 + 31529347 = 31529846

Showing the first eight; more decompositions exist.
