Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608412, here are decompositions:

71 + 31608341 = 31608412
149 + 31608263 = 31608412
263 + 31608149 = 31608412
281 + 31608131 = 31608412
383 + 31608029 = 31608412
443 + 31607969 = 31608412
491 + 31607921 = 31608412
503 + 31607909 = 31608412

Showing the first eight; more decompositions exist.
