Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607976, here are decompositions:

5 + 31607971 = 31607976
7 + 31607969 = 31607976
67 + 31607909 = 31607976
73 + 31607903 = 31607976
79 + 31607897 = 31607976
107 + 31607869 = 31607976
109 + 31607867 = 31607976
137 + 31607839 = 31607976

Showing the first eight; more decompositions exist.
