Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588332, here are decompositions:

11 + 31588321 = 31588332
19 + 31588313 = 31588332
29 + 31588303 = 31588332
79 + 31588253 = 31588332
131 + 31588201 = 31588332
229 + 31588103 = 31588332
271 + 31588061 = 31588332
313 + 31588019 = 31588332

Showing the first eight; more decompositions exist.
