Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594698, here are decompositions:

7 + 31594691 = 31594698
17 + 31594681 = 31594698
71 + 31594627 = 31594698
89 + 31594609 = 31594698
101 + 31594597 = 31594698
151 + 31594547 = 31594698
197 + 31594501 = 31594698
269 + 31594429 = 31594698

Showing the first eight; more decompositions exist.
