Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496946, here are decompositions:

29 + 31496917 = 31496946
73 + 31496873 = 31496946
83 + 31496863 = 31496946
127 + 31496819 = 31496946
137 + 31496809 = 31496946
163 + 31496783 = 31496946
167 + 31496779 = 31496946
227 + 31496719 = 31496946

Showing the first eight; more decompositions exist.
