Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582774, here are decompositions:

17 + 31582757 = 31582774
101 + 31582673 = 31582774
107 + 31582667 = 31582774
173 + 31582601 = 31582774
227 + 31582547 = 31582774
557 + 31582217 = 31582774
653 + 31582121 = 31582774
677 + 31582097 = 31582774

Showing the first eight; more decompositions exist.
