Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520332, here are decompositions:

23 + 31520309 = 31520332
89 + 31520243 = 31520332
131 + 31520201 = 31520332
191 + 31520141 = 31520332
443 + 31519889 = 31520332
509 + 31519823 = 31520332
563 + 31519769 = 31520332
653 + 31519679 = 31520332

Showing the first eight; more decompositions exist.
