Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583416, here are decompositions:

3 + 31583413 = 31583416
257 + 31583159 = 31583416
269 + 31583147 = 31583416
383 + 31583033 = 31583416
467 + 31582949 = 31583416
479 + 31582937 = 31583416
503 + 31582913 = 31583416
509 + 31582907 = 31583416

Showing the first eight; more decompositions exist.
