Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706866, here are decompositions:

13 + 8706853 = 8706866
37 + 8706829 = 8706866
43 + 8706823 = 8706866
73 + 8706793 = 8706866
139 + 8706727 = 8706866
199 + 8706667 = 8706866
313 + 8706553 = 8706866
409 + 8706457 = 8706866

Showing the first eight; more decompositions exist.
