Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613030, here are decompositions:

3 + 31613027 = 31613030
61 + 31612969 = 31613030
79 + 31612951 = 31613030
139 + 31612891 = 31613030
157 + 31612873 = 31613030
199 + 31612831 = 31613030
271 + 31612759 = 31613030
277 + 31612753 = 31613030

Showing the first eight; more decompositions exist.
