Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627584, here are decompositions:

7 + 31627577 = 31627584
11 + 31627573 = 31627584
17 + 31627567 = 31627584
41 + 31627543 = 31627584
47 + 31627537 = 31627584
73 + 31627511 = 31627584
83 + 31627501 = 31627584
101 + 31627483 = 31627584

Showing the first eight; more decompositions exist.
