Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496886, here are decompositions:

13 + 31496873 = 31496886
23 + 31496863 = 31496886
59 + 31496827 = 31496886
67 + 31496819 = 31496886
103 + 31496783 = 31496886
107 + 31496779 = 31496886
167 + 31496719 = 31496886
193 + 31496693 = 31496886

Showing the first eight; more decompositions exist.
