Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583524, here are decompositions:

3 + 31583521 = 31583524
17 + 31583507 = 31583524
47 + 31583477 = 31583524
101 + 31583423 = 31583524
173 + 31583351 = 31583524
353 + 31583171 = 31583524
443 + 31583081 = 31583524
491 + 31583033 = 31583524

Showing the first eight; more decompositions exist.
