Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496982, here are decompositions:

5 + 31496977 = 31496982
19 + 31496963 = 31496982
61 + 31496921 = 31496982
109 + 31496873 = 31496982
163 + 31496819 = 31496982
173 + 31496809 = 31496982
191 + 31496791 = 31496982
199 + 31496783 = 31496982

Showing the first eight; more decompositions exist.
