Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607404, here are decompositions:

5 + 31607399 = 31607404
41 + 31607363 = 31607404
47 + 31607357 = 31607404
107 + 31607297 = 31607404
113 + 31607291 = 31607404
167 + 31607237 = 31607404
197 + 31607207 = 31607404
251 + 31607153 = 31607404

Showing the first eight; more decompositions exist.
