Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608734, here are decompositions:

7 + 31608727 = 31608734
13 + 31608721 = 31608734
37 + 31608697 = 31608734
67 + 31608667 = 31608734
307 + 31608427 = 31608734
397 + 31608337 = 31608734
433 + 31608301 = 31608734
463 + 31608271 = 31608734

Showing the first eight; more decompositions exist.
