Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582674, here are decompositions:

7 + 31582667 = 31582674
41 + 31582633 = 31582674
43 + 31582631 = 31582674
47 + 31582627 = 31582674
61 + 31582613 = 31582674
73 + 31582601 = 31582674
127 + 31582547 = 31582674
257 + 31582417 = 31582674

Showing the first eight; more decompositions exist.
