Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564596, here are decompositions:

5 + 31564591 = 31564596
79 + 31564517 = 31564596
137 + 31564459 = 31564596
149 + 31564447 = 31564596
157 + 31564439 = 31564596
163 + 31564433 = 31564596
263 + 31564333 = 31564596
269 + 31564327 = 31564596

Showing the first eight; more decompositions exist.
