Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588582, here are decompositions:

59 + 31588523 = 31588582
89 + 31588493 = 31588582
251 + 31588331 = 31588582
269 + 31588313 = 31588582
383 + 31588199 = 31588582
479 + 31588103 = 31588582
521 + 31588061 = 31588582
563 + 31588019 = 31588582

Showing the first eight; more decompositions exist.
