Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607608, here are decompositions:

29 + 31607579 = 31607608
251 + 31607357 = 31607608
281 + 31607327 = 31607608
311 + 31607297 = 31607608
317 + 31607291 = 31607608
401 + 31607207 = 31607608
521 + 31607087 = 31607608
569 + 31607039 = 31607608

Showing the first eight; more decompositions exist.
