Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450684, here are decompositions:

17 + 31450667 = 31450684
71 + 31450613 = 31450684
101 + 31450583 = 31450684
107 + 31450577 = 31450684
197 + 31450487 = 31450684
233 + 31450451 = 31450684
257 + 31450427 = 31450684
263 + 31450421 = 31450684

Showing the first eight; more decompositions exist.
