Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515594, here are decompositions:

17 + 31515577 = 31515594
31 + 31515563 = 31515594
37 + 31515557 = 31515594
181 + 31515413 = 31515594
193 + 31515401 = 31515594
211 + 31515383 = 31515594
241 + 31515353 = 31515594
277 + 31515317 = 31515594

Showing the first eight; more decompositions exist.
