Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588594, here are decompositions:

71 + 31588523 = 31588594
101 + 31588493 = 31588594
131 + 31588463 = 31588594
227 + 31588367 = 31588594
263 + 31588331 = 31588594
281 + 31588313 = 31588594
347 + 31588247 = 31588594
491 + 31588103 = 31588594

Showing the first eight; more decompositions exist.
