Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627574, here are decompositions:

7 + 31627567 = 31627574
31 + 31627543 = 31627574
37 + 31627537 = 31627574
73 + 31627501 = 31627574
163 + 31627411 = 31627574
241 + 31627333 = 31627574
271 + 31627303 = 31627574
313 + 31627261 = 31627574

Showing the first eight; more decompositions exist.
