Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608532, here are decompositions:

3 + 31608529 = 31608532
5 + 31608527 = 31608532
83 + 31608449 = 31608532
191 + 31608341 = 31608532
269 + 31608263 = 31608532
383 + 31608149 = 31608532
401 + 31608131 = 31608532
491 + 31608041 = 31608532

Showing the first eight; more decompositions exist.
