Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594760, here are decompositions:

3 + 31594757 = 31594760
13 + 31594747 = 31594760
31 + 31594729 = 31594760
61 + 31594699 = 31594760
79 + 31594681 = 31594760
151 + 31594609 = 31594760
163 + 31594597 = 31594760
181 + 31594579 = 31594760

Showing the first eight; more decompositions exist.
