Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497314, here are decompositions:

31 + 31497283 = 31497314
127 + 31497187 = 31497314
157 + 31497157 = 31497314
181 + 31497133 = 31497314
307 + 31497007 = 31497314
313 + 31497001 = 31497314
337 + 31496977 = 31497314
367 + 31496947 = 31497314

Showing the first eight; more decompositions exist.
