Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583502, here are decompositions:

53 + 31583449 = 31583502
79 + 31583423 = 31583502
89 + 31583413 = 31583502
149 + 31583353 = 31583502
151 + 31583351 = 31583502
179 + 31583323 = 31583502
233 + 31583269 = 31583502
331 + 31583171 = 31583502

Showing the first eight; more decompositions exist.
