Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613072, here are decompositions:

19 + 31613053 = 31613072
103 + 31612969 = 31613072
181 + 31612891 = 31613072
199 + 31612873 = 31613072
241 + 31612831 = 31613072
313 + 31612759 = 31613072
409 + 31612663 = 31613072
499 + 31612573 = 31613072

Showing the first eight; more decompositions exist.
