Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583726, here are decompositions:

67 + 31583659 = 31583726
199 + 31583527 = 31583726
277 + 31583449 = 31583726
313 + 31583413 = 31583726
373 + 31583353 = 31583726
457 + 31583269 = 31583726
829 + 31582897 = 31583726
907 + 31582819 = 31583726

Showing the first eight; more decompositions exist.
