Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583632, here are decompositions:

5 + 31583627 = 31583632
11 + 31583621 = 31583632
71 + 31583561 = 31583632
83 + 31583549 = 31583632
281 + 31583351 = 31583632
461 + 31583171 = 31583632
599 + 31583033 = 31583632
683 + 31582949 = 31583632

Showing the first eight; more decompositions exist.
