Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564714, here are decompositions:

53 + 31564661 = 31564714
101 + 31564613 = 31564714
197 + 31564517 = 31564714
281 + 31564433 = 31564714
353 + 31564361 = 31564714
383 + 31564331 = 31564714
443 + 31564271 = 31564714
557 + 31564157 = 31564714

Showing the first eight; more decompositions exist.
