Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607476, here are decompositions:

3 + 31607473 = 31607476
29 + 31607447 = 31607476
53 + 31607423 = 31607476
113 + 31607363 = 31607476
149 + 31607327 = 31607476
167 + 31607309 = 31607476
179 + 31607297 = 31607476
239 + 31607237 = 31607476

Showing the first eight; more decompositions exist.
