Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583744, here are decompositions:

43 + 31583701 = 31583744
103 + 31583641 = 31583744
223 + 31583521 = 31583744
307 + 31583437 = 31583744
331 + 31583413 = 31583744
421 + 31583323 = 31583744
463 + 31583281 = 31583744
487 + 31583257 = 31583744

Showing the first eight; more decompositions exist.
