Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607470, here are decompositions:

23 + 31607447 = 31607470
47 + 31607423 = 31607470
71 + 31607399 = 31607470
107 + 31607363 = 31607470
113 + 31607357 = 31607470
173 + 31607297 = 31607470
179 + 31607291 = 31607470
233 + 31607237 = 31607470

Showing the first eight; more decompositions exist.
