Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583536, here are decompositions:

29 + 31583507 = 31583536
59 + 31583477 = 31583536
113 + 31583423 = 31583536
389 + 31583147 = 31583536
449 + 31583087 = 31583536
503 + 31583033 = 31583536
587 + 31582949 = 31583536
599 + 31582937 = 31583536

Showing the first eight; more decompositions exist.
