Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607306, here are decompositions:

7 + 31607299 = 31607306
13 + 31607293 = 31607306
43 + 31607263 = 31607306
79 + 31607227 = 31607306
349 + 31606957 = 31607306
727 + 31606579 = 31607306
769 + 31606537 = 31607306
877 + 31606429 = 31607306

Showing the first eight; more decompositions exist.
