Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497056, here are decompositions:

67 + 31496989 = 31497056
79 + 31496977 = 31497056
109 + 31496947 = 31497056
139 + 31496917 = 31497056
193 + 31496863 = 31497056
229 + 31496827 = 31497056
277 + 31496779 = 31497056
337 + 31496719 = 31497056

Showing the first eight; more decompositions exist.
