Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608098, here are decompositions:

7 + 31608091 = 31608098
31 + 31608067 = 31608098
37 + 31608061 = 31608098
61 + 31608037 = 31608098
127 + 31607971 = 31608098
229 + 31607869 = 31608098
241 + 31607857 = 31608098
307 + 31607791 = 31608098

Showing the first eight; more decompositions exist.
