Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582044, here are decompositions:

7 + 31582037 = 31582044
17 + 31582027 = 31582044
23 + 31582021 = 31582044
41 + 31582003 = 31582044
47 + 31581997 = 31582044
61 + 31581983 = 31582044
71 + 31581973 = 31582044
83 + 31581961 = 31582044

Showing the first eight; more decompositions exist.
