Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588674, here are decompositions:

17 + 31588657 = 31588674
31 + 31588643 = 31588674
43 + 31588631 = 31588674
67 + 31588607 = 31588674
71 + 31588603 = 31588674
113 + 31588561 = 31588674
151 + 31588523 = 31588674
181 + 31588493 = 31588674

Showing the first eight; more decompositions exist.
