Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608832, here are decompositions:

11 + 31608821 = 31608832
53 + 31608779 = 31608832
83 + 31608749 = 31608832
383 + 31608449 = 31608832
491 + 31608341 = 31608832
569 + 31608263 = 31608832
683 + 31608149 = 31608832
701 + 31608131 = 31608832

Showing the first eight; more decompositions exist.
