Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583658, here are decompositions:

17 + 31583641 = 31583658
31 + 31583627 = 31583658
37 + 31583621 = 31583658
61 + 31583597 = 31583658
97 + 31583561 = 31583658
109 + 31583549 = 31583658
131 + 31583527 = 31583658
137 + 31583521 = 31583658

Showing the first eight; more decompositions exist.
