Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564716, here are decompositions:

47 + 31564669 = 31564716
59 + 31564657 = 31564716
67 + 31564649 = 31564716
103 + 31564613 = 31564716
199 + 31564517 = 31564716
257 + 31564459 = 31564716
269 + 31564447 = 31564716
277 + 31564439 = 31564716

Showing the first eight; more decompositions exist.
