Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583544, here are decompositions:

17 + 31583527 = 31583544
23 + 31583521 = 31583544
37 + 31583507 = 31583544
67 + 31583477 = 31583544
107 + 31583437 = 31583544
131 + 31583413 = 31583544
191 + 31583353 = 31583544
193 + 31583351 = 31583544

Showing the first eight; more decompositions exist.
