Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607464, here are decompositions:

3 + 31607461 = 31607464
17 + 31607447 = 31607464
41 + 31607423 = 31607464
101 + 31607363 = 31607464
107 + 31607357 = 31607464
137 + 31607327 = 31607464
167 + 31607297 = 31607464
173 + 31607291 = 31607464

Showing the first eight; more decompositions exist.
