Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594600, here are decompositions:

3 + 31594597 = 31594600
17 + 31594583 = 31594600
47 + 31594553 = 31594600
53 + 31594547 = 31594600
137 + 31594463 = 31594600
179 + 31594421 = 31594600
227 + 31594373 = 31594600
269 + 31594331 = 31594600

Showing the first eight; more decompositions exist.
