Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583804, here are decompositions:

103 + 31583701 = 31583804
163 + 31583641 = 31583804
277 + 31583527 = 31583804
283 + 31583521 = 31583804
367 + 31583437 = 31583804
523 + 31583281 = 31583804
547 + 31583257 = 31583804
673 + 31583131 = 31583804

Showing the first eight; more decompositions exist.
