Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627554, here are decompositions:

11 + 31627543 = 31627554
17 + 31627537 = 31627554
43 + 31627511 = 31627554
53 + 31627501 = 31627554
71 + 31627483 = 31627554
163 + 31627391 = 31627554
181 + 31627373 = 31627554
197 + 31627357 = 31627554

Showing the first eight; more decompositions exist.
