Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582680, here are decompositions:

7 + 31582673 = 31582680
13 + 31582667 = 31582680
47 + 31582633 = 31582680
53 + 31582627 = 31582680
67 + 31582613 = 31582680
71 + 31582609 = 31582680
79 + 31582601 = 31582680
127 + 31582553 = 31582680

Showing the first eight; more decompositions exist.
