Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627450, here are decompositions:

59 + 31627391 = 31627450
131 + 31627319 = 31627450
233 + 31627217 = 31627450
317 + 31627133 = 31627450
359 + 31627091 = 31627450
443 + 31627007 = 31627450
557 + 31626893 = 31627450
593 + 31626857 = 31627450

Showing the first eight; more decompositions exist.
