Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460168, here are decompositions:

31 + 31460137 = 31460168
151 + 31460017 = 31460168
277 + 31459891 = 31460168
409 + 31459759 = 31460168
547 + 31459621 = 31460168
769 + 31459399 = 31460168
811 + 31459357 = 31460168
829 + 31459339 = 31460168

Showing the first eight; more decompositions exist.
