Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582794, here are decompositions:

13 + 31582781 = 31582794
17 + 31582777 = 31582794
37 + 31582757 = 31582794
127 + 31582667 = 31582794
163 + 31582631 = 31582794
167 + 31582627 = 31582794
181 + 31582613 = 31582794
193 + 31582601 = 31582794

Showing the first eight; more decompositions exist.
