Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686020, here are decompositions:

17 + 8686003 = 8686020
19 + 8686001 = 8686020
41 + 8685979 = 8686020
53 + 8685967 = 8686020
59 + 8685961 = 8686020
67 + 8685953 = 8686020
71 + 8685949 = 8686020
97 + 8685923 = 8686020

Showing the first eight; more decompositions exist.
