Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626904, here are decompositions:

5 + 31626899 = 31626904
11 + 31626893 = 31626904
47 + 31626857 = 31626904
107 + 31626797 = 31626904
137 + 31626767 = 31626904
347 + 31626557 = 31626904
443 + 31626461 = 31626904
467 + 31626437 = 31626904

Showing the first eight; more decompositions exist.
