Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564444, here are decompositions:

5 + 31564439 = 31564444
11 + 31564433 = 31564444
53 + 31564391 = 31564444
83 + 31564361 = 31564444
113 + 31564331 = 31564444
173 + 31564271 = 31564444
281 + 31564163 = 31564444
311 + 31564133 = 31564444

Showing the first eight; more decompositions exist.
