Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583332, here are decompositions:

173 + 31583159 = 31583332
251 + 31583081 = 31583332
281 + 31583051 = 31583332
383 + 31582949 = 31583332
401 + 31582931 = 31583332
419 + 31582913 = 31583332
509 + 31582823 = 31583332
593 + 31582739 = 31583332

Showing the first eight; more decompositions exist.
