Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627586, here are decompositions:

13 + 31627573 = 31627586
19 + 31627567 = 31627586
43 + 31627543 = 31627586
103 + 31627483 = 31627586
229 + 31627357 = 31627586
283 + 31627303 = 31627586
337 + 31627249 = 31627586
349 + 31627237 = 31627586

Showing the first eight; more decompositions exist.
