Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564704, here are decompositions:

43 + 31564661 = 31564704
47 + 31564657 = 31564704
113 + 31564591 = 31564704
173 + 31564531 = 31564704
257 + 31564447 = 31564704
271 + 31564433 = 31564704
313 + 31564391 = 31564704
317 + 31564387 = 31564704

Showing the first eight; more decompositions exist.
