Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608416, here are decompositions:

67 + 31608349 = 31608416
79 + 31608337 = 31608416
97 + 31608319 = 31608416
199 + 31608217 = 31608416
283 + 31608133 = 31608416
349 + 31608067 = 31608416
379 + 31608037 = 31608416
547 + 31607869 = 31608416

Showing the first eight; more decompositions exist.
