Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594562, here are decompositions:

61 + 31594501 = 31594562
73 + 31594489 = 31594562
163 + 31594399 = 31594562
211 + 31594351 = 31594562
229 + 31594333 = 31594562
499 + 31594063 = 31594562
523 + 31594039 = 31594562
619 + 31593943 = 31594562

Showing the first eight; more decompositions exist.
