Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477166, here are decompositions:

3 + 31477163 = 31477166
67 + 31477099 = 31477166
103 + 31477063 = 31477166
109 + 31477057 = 31477166
139 + 31477027 = 31477166
313 + 31476853 = 31477166
337 + 31476829 = 31477166
367 + 31476799 = 31477166

Showing the first eight; more decompositions exist.
