Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627752, here are decompositions:

31 + 31627721 = 31627752
103 + 31627649 = 31627752
113 + 31627639 = 31627752
151 + 31627601 = 31627752
179 + 31627573 = 31627752
193 + 31627559 = 31627752
241 + 31627511 = 31627752
251 + 31627501 = 31627752

Showing the first eight; more decompositions exist.
