Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496958, here are decompositions:

11 + 31496947 = 31496958
37 + 31496921 = 31496958
41 + 31496917 = 31496958
131 + 31496827 = 31496958
139 + 31496819 = 31496958
149 + 31496809 = 31496958
167 + 31496791 = 31496958
179 + 31496779 = 31496958

Showing the first eight; more decompositions exist.
