Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627516, here are decompositions:

5 + 31627511 = 31627516
197 + 31627319 = 31627516
227 + 31627289 = 31627516
269 + 31627247 = 31627516
383 + 31627133 = 31627516
443 + 31627073 = 31627516
509 + 31627007 = 31627516
617 + 31626899 = 31627516

Showing the first eight; more decompositions exist.
