Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576314, here are decompositions:

31 + 31576283 = 31576314
47 + 31576267 = 31576314
53 + 31576261 = 31576314
61 + 31576253 = 31576314
73 + 31576241 = 31576314
83 + 31576231 = 31576314
103 + 31576211 = 31576314
113 + 31576201 = 31576314

Showing the first eight; more decompositions exist.
