Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594636, here are decompositions:

23 + 31594613 = 31594636
53 + 31594583 = 31594636
83 + 31594553 = 31594636
89 + 31594547 = 31594636
173 + 31594463 = 31594636
263 + 31594373 = 31594636
389 + 31594247 = 31594636
443 + 31594193 = 31594636

Showing the first eight; more decompositions exist.
