Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613702, here are decompositions:

73 + 31613629 = 31613702
79 + 31613623 = 31613702
151 + 31613551 = 31613702
163 + 31613539 = 31613702
733 + 31612969 = 31613702
751 + 31612951 = 31613702
811 + 31612891 = 31613702
829 + 31612873 = 31613702

Showing the first eight; more decompositions exist.
