Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530832, here are decompositions:

5 + 31530827 = 31530832
59 + 31530773 = 31530832
131 + 31530701 = 31530832
149 + 31530683 = 31530832
173 + 31530659 = 31530832
191 + 31530641 = 31530832
239 + 31530593 = 31530832
353 + 31530479 = 31530832

Showing the first eight; more decompositions exist.
