Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583608, here are decompositions:

11 + 31583597 = 31583608
47 + 31583561 = 31583608
59 + 31583549 = 31583608
101 + 31583507 = 31583608
131 + 31583477 = 31583608
257 + 31583351 = 31583608
449 + 31583159 = 31583608
461 + 31583147 = 31583608

Showing the first eight; more decompositions exist.
