Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608350, here are decompositions:

13 + 31608337 = 31608350
31 + 31608319 = 31608350
79 + 31608271 = 31608350
181 + 31608169 = 31608350
283 + 31608067 = 31608350
313 + 31608037 = 31608350
337 + 31608013 = 31608350
379 + 31607971 = 31608350

Showing the first eight; more decompositions exist.
