Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588612, here are decompositions:

5 + 31588607 = 31588612
89 + 31588523 = 31588612
149 + 31588463 = 31588612
173 + 31588439 = 31588612
281 + 31588331 = 31588612
359 + 31588253 = 31588612
509 + 31588103 = 31588612
593 + 31588019 = 31588612

Showing the first eight; more decompositions exist.
