Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627664, here are decompositions:

37 + 31627627 = 31627664
97 + 31627567 = 31627664
127 + 31627537 = 31627664
163 + 31627501 = 31627664
181 + 31627483 = 31627664
307 + 31627357 = 31627664
331 + 31627333 = 31627664
421 + 31627243 = 31627664

Showing the first eight; more decompositions exist.
