Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583634, here are decompositions:

7 + 31583627 = 31583634
13 + 31583621 = 31583634
37 + 31583597 = 31583634
73 + 31583561 = 31583634
107 + 31583527 = 31583634
113 + 31583521 = 31583634
127 + 31583507 = 31583634
157 + 31583477 = 31583634

Showing the first eight; more decompositions exist.
