Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496930, here are decompositions:

13 + 31496917 = 31496930
67 + 31496863 = 31496930
103 + 31496827 = 31496930
139 + 31496791 = 31496930
151 + 31496779 = 31496930
211 + 31496719 = 31496930
331 + 31496599 = 31496930
337 + 31496593 = 31496930

Showing the first eight; more decompositions exist.
