Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499314, here are decompositions:

3 + 31499311 = 31499314
5 + 31499309 = 31499314
17 + 31499297 = 31499314
23 + 31499291 = 31499314
47 + 31499267 = 31499314
83 + 31499231 = 31499314
131 + 31499183 = 31499314
251 + 31499063 = 31499314

Showing the first eight; more decompositions exist.
