Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582996, here are decompositions:

47 + 31582949 = 31582996
59 + 31582937 = 31582996
83 + 31582913 = 31582996
89 + 31582907 = 31582996
149 + 31582847 = 31582996
173 + 31582823 = 31582996
239 + 31582757 = 31582996
257 + 31582739 = 31582996

Showing the first eight; more decompositions exist.
