Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450492, here are decompositions:

5 + 31450487 = 31450492
41 + 31450451 = 31450492
71 + 31450421 = 31450492
83 + 31450409 = 31450492
179 + 31450313 = 31450492
389 + 31450103 = 31450492
431 + 31450061 = 31450492
449 + 31450043 = 31450492

Showing the first eight; more decompositions exist.
