Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594702, here are decompositions:

3 + 31594699 = 31594702
11 + 31594691 = 31594702
89 + 31594613 = 31594702
149 + 31594553 = 31594702
239 + 31594463 = 31594702
281 + 31594421 = 31594702
431 + 31594271 = 31594702
509 + 31594193 = 31594702

Showing the first eight; more decompositions exist.
