Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594558, here are decompositions:

5 + 31594553 = 31594558
11 + 31594547 = 31594558
137 + 31594421 = 31594558
227 + 31594331 = 31594558
311 + 31594247 = 31594558
461 + 31594097 = 31594558
509 + 31594049 = 31594558
599 + 31593959 = 31594558

Showing the first eight; more decompositions exist.
