Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588744, here are decompositions:

71 + 31588673 = 31588744
101 + 31588643 = 31588744
113 + 31588631 = 31588744
137 + 31588607 = 31588744
251 + 31588493 = 31588744
281 + 31588463 = 31588744
431 + 31588313 = 31588744
491 + 31588253 = 31588744

Showing the first eight; more decompositions exist.
