Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496868, here are decompositions:

5 + 31496863 = 31496868
41 + 31496827 = 31496868
59 + 31496809 = 31496868
89 + 31496779 = 31496868
127 + 31496741 = 31496868
149 + 31496719 = 31496868
191 + 31496677 = 31496868
197 + 31496671 = 31496868

Showing the first eight; more decompositions exist.
