Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496922, here are decompositions:

5 + 31496917 = 31496922
59 + 31496863 = 31496922
103 + 31496819 = 31496922
113 + 31496809 = 31496922
131 + 31496791 = 31496922
139 + 31496783 = 31496922
181 + 31496741 = 31496922
229 + 31496693 = 31496922

Showing the first eight; more decompositions exist.
