Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564662, here are decompositions:

5 + 31564657 = 31564662
13 + 31564649 = 31564662
23 + 31564639 = 31564662
71 + 31564591 = 31564662
131 + 31564531 = 31564662
223 + 31564439 = 31564662
229 + 31564433 = 31564662
271 + 31564391 = 31564662

Showing the first eight; more decompositions exist.
