Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594882, here are decompositions:

5 + 31594877 = 31594882
71 + 31594811 = 31594882
83 + 31594799 = 31594882
113 + 31594769 = 31594882
191 + 31594691 = 31594882
269 + 31594613 = 31594882
419 + 31594463 = 31594882
461 + 31594421 = 31594882

Showing the first eight; more decompositions exist.
