Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496910, here are decompositions:

37 + 31496873 = 31496910
47 + 31496863 = 31496910
83 + 31496827 = 31496910
101 + 31496809 = 31496910
127 + 31496783 = 31496910
131 + 31496779 = 31496910
191 + 31496719 = 31496910
233 + 31496677 = 31496910

Showing the first eight; more decompositions exist.
