Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588314, here are decompositions:

7 + 31588307 = 31588314
11 + 31588303 = 31588314
47 + 31588267 = 31588314
61 + 31588253 = 31588314
67 + 31588247 = 31588314
113 + 31588201 = 31588314
157 + 31588157 = 31588314
211 + 31588103 = 31588314

Showing the first eight; more decompositions exist.
