Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607494, here are decompositions:

5 + 31607489 = 31607494
47 + 31607447 = 31607494
71 + 31607423 = 31607494
131 + 31607363 = 31607494
137 + 31607357 = 31607494
167 + 31607327 = 31607494
197 + 31607297 = 31607494
257 + 31607237 = 31607494

Showing the first eight; more decompositions exist.
