Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582956, here are decompositions:

5 + 31582951 = 31582956
7 + 31582949 = 31582956
19 + 31582937 = 31582956
43 + 31582913 = 31582956
59 + 31582897 = 31582956
109 + 31582847 = 31582956
137 + 31582819 = 31582956
179 + 31582777 = 31582956

Showing the first eight; more decompositions exist.
