Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718986, here are decompositions:

13 + 8718973 = 8718986
37 + 8718949 = 8718986
79 + 8718907 = 8718986
109 + 8718877 = 8718986
127 + 8718859 = 8718986
163 + 8718823 = 8718986
193 + 8718793 = 8718986
229 + 8718757 = 8718986

Showing the first eight; more decompositions exist.
