Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608074, here are decompositions:

7 + 31608067 = 31608074
13 + 31608061 = 31608074
37 + 31608037 = 31608074
61 + 31608013 = 31608074
103 + 31607971 = 31608074
283 + 31607791 = 31608074
523 + 31607551 = 31608074
571 + 31607503 = 31608074

Showing the first eight; more decompositions exist.
