Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31016, here are decompositions:

3 + 31013 = 31016
67 + 30949 = 31016
79 + 30937 = 31016
157 + 30859 = 31016
163 + 30853 = 31016
199 + 30817 = 31016
313 + 30703 = 31016
367 + 30649 = 31016

Showing the first eight; more decompositions exist.
