Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607356, here are decompositions:

29 + 31607327 = 31607356
47 + 31607309 = 31607356
59 + 31607297 = 31607356
149 + 31607207 = 31607356
269 + 31607087 = 31607356
317 + 31607039 = 31607356
359 + 31606997 = 31607356
383 + 31606973 = 31607356

Showing the first eight; more decompositions exist.
