Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594688, here are decompositions:

7 + 31594681 = 31594688
61 + 31594627 = 31594688
79 + 31594609 = 31594688
109 + 31594579 = 31594688
199 + 31594489 = 31594688
337 + 31594351 = 31594688
379 + 31594309 = 31594688
607 + 31594081 = 31594688

Showing the first eight; more decompositions exist.
