Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583446, here are decompositions:

23 + 31583423 = 31583446
359 + 31583087 = 31583446
509 + 31582937 = 31583446
599 + 31582847 = 31583446
773 + 31582673 = 31583446
857 + 31582589 = 31583446
887 + 31582559 = 31583446
1109 + 31582337 = 31583446

Showing the first eight; more decompositions exist.
