Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594874, here are decompositions:

7 + 31594867 = 31594874
13 + 31594861 = 31594874
61 + 31594813 = 31594874
67 + 31594807 = 31594874
127 + 31594747 = 31594874
193 + 31594681 = 31594874
277 + 31594597 = 31594874
373 + 31594501 = 31594874

Showing the first eight; more decompositions exist.
