Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607904, here are decompositions:

7 + 31607897 = 31607904
37 + 31607867 = 31607904
47 + 31607857 = 31607904
73 + 31607831 = 31607904
113 + 31607791 = 31607904
157 + 31607747 = 31607904
233 + 31607671 = 31607904
353 + 31607551 = 31607904

Showing the first eight; more decompositions exist.
