Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582062, here are decompositions:

13 + 31582049 = 31582062
19 + 31582043 = 31582062
41 + 31582021 = 31582062
59 + 31582003 = 31582062
79 + 31581983 = 31582062
89 + 31581973 = 31582062
101 + 31581961 = 31582062
151 + 31581911 = 31582062

Showing the first eight; more decompositions exist.
