Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582576, here are decompositions:

17 + 31582559 = 31582576
23 + 31582553 = 31582576
29 + 31582547 = 31582576
167 + 31582409 = 31582576
173 + 31582403 = 31582576
239 + 31582337 = 31582576
257 + 31582319 = 31582576
359 + 31582217 = 31582576

Showing the first eight; more decompositions exist.
