Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583382, here are decompositions:

29 + 31583353 = 31583382
31 + 31583351 = 31583382
59 + 31583323 = 31583382
101 + 31583281 = 31583382
113 + 31583269 = 31583382
211 + 31583171 = 31583382
223 + 31583159 = 31583382
251 + 31583131 = 31583382

Showing the first eight; more decompositions exist.
