Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496808, here are decompositions:

17 + 31496791 = 31496808
29 + 31496779 = 31496808
67 + 31496741 = 31496808
89 + 31496719 = 31496808
131 + 31496677 = 31496808
137 + 31496671 = 31496808
139 + 31496669 = 31496808
197 + 31496611 = 31496808

Showing the first eight; more decompositions exist.
