Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583858, here are decompositions:

79 + 31583779 = 31583858
109 + 31583749 = 31583858
157 + 31583701 = 31583858
199 + 31583659 = 31583858
331 + 31583527 = 31583858
337 + 31583521 = 31583858
349 + 31583509 = 31583858
409 + 31583449 = 31583858

Showing the first eight; more decompositions exist.
