Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582822, here are decompositions:

3 + 31582819 = 31582822
41 + 31582781 = 31582822
83 + 31582739 = 31582822
149 + 31582673 = 31582822
191 + 31582631 = 31582822
233 + 31582589 = 31582822
263 + 31582559 = 31582822
269 + 31582553 = 31582822

Showing the first eight; more decompositions exist.
