Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583494, here are decompositions:

17 + 31583477 = 31583494
71 + 31583423 = 31583494
347 + 31583147 = 31583494
443 + 31583051 = 31583494
461 + 31583033 = 31583494
557 + 31582937 = 31583494
563 + 31582931 = 31583494
587 + 31582907 = 31583494

Showing the first eight; more decompositions exist.
