Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627536, here are decompositions:

53 + 31627483 = 31627536
163 + 31627373 = 31627536
179 + 31627357 = 31627536
233 + 31627303 = 31627536
293 + 31627243 = 31627536
463 + 31627073 = 31627536
467 + 31627069 = 31627536
503 + 31627033 = 31627536

Showing the first eight; more decompositions exist.
