Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574652, here are decompositions:

13 + 31574639 = 31574652
89 + 31574563 = 31574652
163 + 31574489 = 31574652
173 + 31574479 = 31574652
199 + 31574453 = 31574652
223 + 31574429 = 31574652
233 + 31574419 = 31574652
283 + 31574369 = 31574652

Showing the first eight; more decompositions exist.
