Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608704, here are decompositions:

7 + 31608697 = 31608704
37 + 31608667 = 31608704
223 + 31608481 = 31608704
277 + 31608427 = 31608704
367 + 31608337 = 31608704
433 + 31608271 = 31608704
487 + 31608217 = 31608704
541 + 31608163 = 31608704

Showing the first eight; more decompositions exist.
