Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613078, here are decompositions:

97 + 31612981 = 31613078
109 + 31612969 = 31613078
127 + 31612951 = 31613078
139 + 31612939 = 31613078
331 + 31612747 = 31613078
349 + 31612729 = 31613078
457 + 31612621 = 31613078
547 + 31612531 = 31613078

Showing the first eight; more decompositions exist.
