Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582696, here are decompositions:

17 + 31582679 = 31582696
23 + 31582673 = 31582696
29 + 31582667 = 31582696
83 + 31582613 = 31582696
107 + 31582589 = 31582696
137 + 31582559 = 31582696
149 + 31582547 = 31582696
293 + 31582403 = 31582696

Showing the first eight; more decompositions exist.
