Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582776, here are decompositions:

19 + 31582757 = 31582776
37 + 31582739 = 31582776
47 + 31582729 = 31582776
97 + 31582679 = 31582776
103 + 31582673 = 31582776
109 + 31582667 = 31582776
149 + 31582627 = 31582776
163 + 31582613 = 31582776

Showing the first eight; more decompositions exist.
