Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594762, here are decompositions:

5 + 31594757 = 31594762
71 + 31594691 = 31594762
149 + 31594613 = 31594762
179 + 31594583 = 31594762
389 + 31594373 = 31594762
431 + 31594331 = 31594762
491 + 31594271 = 31594762
569 + 31594193 = 31594762

Showing the first eight; more decompositions exist.
