Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627518, here are decompositions:

7 + 31627511 = 31627518
17 + 31627501 = 31627518
107 + 31627411 = 31627518
127 + 31627391 = 31627518
199 + 31627319 = 31627518
229 + 31627289 = 31627518
257 + 31627261 = 31627518
269 + 31627249 = 31627518

Showing the first eight; more decompositions exist.
