Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583588, here are decompositions:

61 + 31583527 = 31583588
67 + 31583521 = 31583588
79 + 31583509 = 31583588
139 + 31583449 = 31583588
151 + 31583437 = 31583588
307 + 31583281 = 31583588
331 + 31583257 = 31583588
457 + 31583131 = 31583588

Showing the first eight; more decompositions exist.
