Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583056, here are decompositions:

5 + 31583051 = 31583056
23 + 31583033 = 31583056
107 + 31582949 = 31583056
149 + 31582907 = 31583056
233 + 31582823 = 31583056
317 + 31582739 = 31583056
383 + 31582673 = 31583056
389 + 31582667 = 31583056

Showing the first eight; more decompositions exist.
