Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582846, here are decompositions:

23 + 31582823 = 31582846
89 + 31582757 = 31582846
107 + 31582739 = 31582846
167 + 31582679 = 31582846
173 + 31582673 = 31582846
179 + 31582667 = 31582846
233 + 31582613 = 31582846
257 + 31582589 = 31582846

Showing the first eight; more decompositions exist.
