Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607910, here are decompositions:

7 + 31607903 = 31607910
13 + 31607897 = 31607910
41 + 31607869 = 31607910
43 + 31607867 = 31607910
53 + 31607857 = 31607910
71 + 31607839 = 31607910
79 + 31607831 = 31607910
127 + 31607783 = 31607910

Showing the first eight; more decompositions exist.
