Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477010, here are decompositions:

79 + 31476931 = 31477010
139 + 31476871 = 31477010
157 + 31476853 = 31477010
163 + 31476847 = 31477010
181 + 31476829 = 31477010
211 + 31476799 = 31477010
277 + 31476733 = 31477010
283 + 31476727 = 31477010

Showing the first eight; more decompositions exist.
