Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564446, here are decompositions:

7 + 31564439 = 31564446
13 + 31564433 = 31564446
59 + 31564387 = 31564446
113 + 31564333 = 31564446
197 + 31564249 = 31564446
239 + 31564207 = 31564446
283 + 31564163 = 31564446
307 + 31564139 = 31564446

Showing the first eight; more decompositions exist.
