Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627646, here are decompositions:

7 + 31627639 = 31627646
19 + 31627627 = 31627646
73 + 31627573 = 31627646
79 + 31627567 = 31627646
103 + 31627543 = 31627646
109 + 31627537 = 31627646
163 + 31627483 = 31627646
313 + 31627333 = 31627646

Showing the first eight; more decompositions exist.
