Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697986, here are decompositions:

13 + 8697973 = 8697986
19 + 8697967 = 8697986
43 + 8697943 = 8697986
67 + 8697919 = 8697986
97 + 8697889 = 8697986
127 + 8697859 = 8697986
163 + 8697823 = 8697986
373 + 8697613 = 8697986

Showing the first eight; more decompositions exist.
