Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617836, here are decompositions:

73 + 31617763 = 31617836
79 + 31617757 = 31617836
139 + 31617697 = 31617836
157 + 31617679 = 31617836
163 + 31617673 = 31617836
277 + 31617559 = 31617836
307 + 31617529 = 31617836
379 + 31617457 = 31617836

Showing the first eight; more decompositions exist.
