Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588366, here are decompositions:

53 + 31588313 = 31588366
59 + 31588307 = 31588366
113 + 31588253 = 31588366
167 + 31588199 = 31588366
263 + 31588103 = 31588366
347 + 31588019 = 31588366
443 + 31587923 = 31588366
587 + 31587779 = 31588366

Showing the first eight; more decompositions exist.
