Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608476, here are decompositions:

127 + 31608349 = 31608476
139 + 31608337 = 31608476
157 + 31608319 = 31608476
307 + 31608169 = 31608476
313 + 31608163 = 31608476
409 + 31608067 = 31608476
439 + 31608037 = 31608476
463 + 31608013 = 31608476

Showing the first eight; more decompositions exist.
