Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450498, here are decompositions:

11 + 31450487 = 31450498
47 + 31450451 = 31450498
71 + 31450427 = 31450498
89 + 31450409 = 31450498
227 + 31450271 = 31450498
251 + 31450247 = 31450498
281 + 31450217 = 31450498
467 + 31450031 = 31450498

Showing the first eight; more decompositions exist.
