Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607374, here are decompositions:

11 + 31607363 = 31607374
17 + 31607357 = 31607374
47 + 31607327 = 31607374
83 + 31607291 = 31607374
137 + 31607237 = 31607374
167 + 31607207 = 31607374
173 + 31607201 = 31607374
401 + 31606973 = 31607374

Showing the first eight; more decompositions exist.
