Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496892, here are decompositions:

19 + 31496873 = 31496892
29 + 31496863 = 31496892
73 + 31496819 = 31496892
83 + 31496809 = 31496892
101 + 31496791 = 31496892
109 + 31496783 = 31496892
113 + 31496779 = 31496892
151 + 31496741 = 31496892

Showing the first eight; more decompositions exist.
