Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627652, here are decompositions:

3 + 31627649 = 31627652
13 + 31627639 = 31627652
79 + 31627573 = 31627652
109 + 31627543 = 31627652
151 + 31627501 = 31627652
241 + 31627411 = 31627652
349 + 31627303 = 31627652
409 + 31627243 = 31627652

Showing the first eight; more decompositions exist.
