Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613120, here are decompositions:

3 + 31613117 = 31613120
13 + 31613107 = 31613120
67 + 31613053 = 31613120
139 + 31612981 = 31613120
151 + 31612969 = 31613120
181 + 31612939 = 31613120
229 + 31612891 = 31613120
367 + 31612753 = 31613120

Showing the first eight; more decompositions exist.
