Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550584, here are decompositions:

3 + 31550581 = 31550584
11 + 31550573 = 31550584
41 + 31550543 = 31550584
47 + 31550537 = 31550584
53 + 31550531 = 31550584
113 + 31550471 = 31550584
137 + 31550447 = 31550584
227 + 31550357 = 31550584

Showing the first eight; more decompositions exist.
