Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596908, here are decompositions:

19 + 31596889 = 31596908
61 + 31596847 = 31596908
139 + 31596769 = 31596908
151 + 31596757 = 31596908
157 + 31596751 = 31596908
199 + 31596709 = 31596908
229 + 31596679 = 31596908
271 + 31596637 = 31596908

Showing the first eight; more decompositions exist.
