Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582056, here are decompositions:

7 + 31582049 = 31582056
13 + 31582043 = 31582056
19 + 31582037 = 31582056
29 + 31582027 = 31582056
53 + 31582003 = 31582056
59 + 31581997 = 31582056
73 + 31581983 = 31582056
83 + 31581973 = 31582056

Showing the first eight; more decompositions exist.
