Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612594, here are decompositions:

5 + 31612589 = 31612594
11 + 31612583 = 31612594
47 + 31612547 = 31612594
107 + 31612487 = 31612594
113 + 31612481 = 31612594
281 + 31612313 = 31612594
317 + 31612277 = 31612594
353 + 31612241 = 31612594

Showing the first eight; more decompositions exist.
