Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588966, here are decompositions:

23 + 31588943 = 31588966
257 + 31588709 = 31588966
293 + 31588673 = 31588966
359 + 31588607 = 31588966
443 + 31588523 = 31588966
503 + 31588463 = 31588966
599 + 31588367 = 31588966
653 + 31588313 = 31588966

Showing the first eight; more decompositions exist.
