Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608624, here are decompositions:

37 + 31608587 = 31608624
97 + 31608527 = 31608624
127 + 31608497 = 31608624
197 + 31608427 = 31608624
283 + 31608341 = 31608624
353 + 31608271 = 31608624
457 + 31608167 = 31608624
461 + 31608163 = 31608624

Showing the first eight; more decompositions exist.
