Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627604, here are decompositions:

3 + 31627601 = 31627604
31 + 31627573 = 31627604
37 + 31627567 = 31627604
61 + 31627543 = 31627604
67 + 31627537 = 31627604
103 + 31627501 = 31627604
193 + 31627411 = 31627604
271 + 31627333 = 31627604

Showing the first eight; more decompositions exist.
