Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583896, here are decompositions:

59 + 31583837 = 31583896
167 + 31583729 = 31583896
233 + 31583663 = 31583896
263 + 31583633 = 31583896
269 + 31583627 = 31583896
347 + 31583549 = 31583896
389 + 31583507 = 31583896
419 + 31583477 = 31583896

Showing the first eight; more decompositions exist.
