Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594868, here are decompositions:

7 + 31594861 = 31594868
61 + 31594807 = 31594868
139 + 31594729 = 31594868
241 + 31594627 = 31594868
271 + 31594597 = 31594868
367 + 31594501 = 31594868
379 + 31594489 = 31594868
439 + 31594429 = 31594868

Showing the first eight; more decompositions exist.
