Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564954, here are decompositions:

11 + 31564943 = 31564954
101 + 31564853 = 31564954
173 + 31564781 = 31564954
233 + 31564721 = 31564954
293 + 31564661 = 31564954
521 + 31564433 = 31564954
563 + 31564391 = 31564954
593 + 31564361 = 31564954

Showing the first eight; more decompositions exist.
