Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574682, here are decompositions:

5 + 31574677 = 31574682
11 + 31574671 = 31574682
43 + 31574639 = 31574682
151 + 31574531 = 31574682
193 + 31574489 = 31574682
229 + 31574453 = 31574682
233 + 31574449 = 31574682
239 + 31574443 = 31574682

Showing the first eight; more decompositions exist.
