Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590844, here are decompositions:

3 + 31590841 = 31590844
11 + 31590833 = 31590844
41 + 31590803 = 31590844
53 + 31590791 = 31590844
107 + 31590737 = 31590844
113 + 31590731 = 31590844
227 + 31590617 = 31590844
251 + 31590593 = 31590844

Showing the first eight; more decompositions exist.
