Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607446, here are decompositions:

23 + 31607423 = 31607446
47 + 31607399 = 31607446
83 + 31607363 = 31607446
89 + 31607357 = 31607446
137 + 31607309 = 31607446
149 + 31607297 = 31607446
239 + 31607207 = 31607446
293 + 31607153 = 31607446

Showing the first eight; more decompositions exist.
