Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627556, here are decompositions:

13 + 31627543 = 31627556
19 + 31627537 = 31627556
73 + 31627483 = 31627556
199 + 31627357 = 31627556
223 + 31627333 = 31627556
307 + 31627249 = 31627556
313 + 31627243 = 31627556
487 + 31627069 = 31627556

Showing the first eight; more decompositions exist.
