Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588502, here are decompositions:

19 + 31588483 = 31588502
31 + 31588471 = 31588502
61 + 31588441 = 31588502
103 + 31588399 = 31588502
151 + 31588351 = 31588502
181 + 31588321 = 31588502
199 + 31588303 = 31588502
331 + 31588171 = 31588502

Showing the first eight; more decompositions exist.
