Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686724, here are decompositions:

3 + 8686721 = 8686724
37 + 8686687 = 8686724
73 + 8686651 = 8686724
157 + 8686567 = 8686724
223 + 8686501 = 8686724
433 + 8686291 = 8686724
547 + 8686177 = 8686724
577 + 8686147 = 8686724

Showing the first eight; more decompositions exist.
