Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613048, here are decompositions:

67 + 31612981 = 31613048
79 + 31612969 = 31613048
97 + 31612951 = 31613048
109 + 31612939 = 31613048
157 + 31612891 = 31613048
421 + 31612627 = 31613048
619 + 31612429 = 31613048
739 + 31612309 = 31613048

Showing the first eight; more decompositions exist.
