Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543832, here are decompositions:

3 + 31543829 = 31543832
109 + 31543723 = 31543832
163 + 31543669 = 31543832
379 + 31543453 = 31543832
601 + 31543231 = 31543832
613 + 31543219 = 31543832
823 + 31543009 = 31543832
883 + 31542949 = 31543832

Showing the first eight; more decompositions exist.
