Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588336, here are decompositions:

5 + 31588331 = 31588336
23 + 31588313 = 31588336
29 + 31588307 = 31588336
83 + 31588253 = 31588336
89 + 31588247 = 31588336
137 + 31588199 = 31588336
179 + 31588157 = 31588336
233 + 31588103 = 31588336

Showing the first eight; more decompositions exist.
