Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583508, here are decompositions:

31 + 31583477 = 31583508
59 + 31583449 = 31583508
71 + 31583437 = 31583508
157 + 31583351 = 31583508
227 + 31583281 = 31583508
239 + 31583269 = 31583508
251 + 31583257 = 31583508
337 + 31583171 = 31583508

Showing the first eight; more decompositions exist.
