Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594594, here are decompositions:

11 + 31594583 = 31594594
41 + 31594553 = 31594594
47 + 31594547 = 31594594
131 + 31594463 = 31594594
173 + 31594421 = 31594594
263 + 31594331 = 31594594
347 + 31594247 = 31594594
401 + 31594193 = 31594594

Showing the first eight; more decompositions exist.
