Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582046, here are decompositions:

3 + 31582043 = 31582046
19 + 31582027 = 31582046
43 + 31582003 = 31582046
73 + 31581973 = 31582046
157 + 31581889 = 31582046
163 + 31581883 = 31582046
229 + 31581817 = 31582046
337 + 31581709 = 31582046

Showing the first eight; more decompositions exist.
