Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613432, here are decompositions:

31 + 31613401 = 31613432
241 + 31613191 = 31613432
313 + 31613119 = 31613432
379 + 31613053 = 31613432
463 + 31612969 = 31613432
541 + 31612891 = 31613432
601 + 31612831 = 31613432
673 + 31612759 = 31613432

Showing the first eight; more decompositions exist.
