Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608404, here are decompositions:

67 + 31608337 = 31608404
103 + 31608301 = 31608404
241 + 31608163 = 31608404
271 + 31608133 = 31608404
313 + 31608091 = 31608404
337 + 31608067 = 31608404
367 + 31608037 = 31608404
433 + 31607971 = 31608404

Showing the first eight; more decompositions exist.
