Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496862, here are decompositions:

43 + 31496819 = 31496862
53 + 31496809 = 31496862
71 + 31496791 = 31496862
79 + 31496783 = 31496862
83 + 31496779 = 31496862
191 + 31496671 = 31496862
193 + 31496669 = 31496862
251 + 31496611 = 31496862

Showing the first eight; more decompositions exist.
