Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718866, here are decompositions:

7 + 8718859 = 8718866
43 + 8718823 = 8718866
67 + 8718799 = 8718866
73 + 8718793 = 8718866
109 + 8718757 = 8718866
139 + 8718727 = 8718866
157 + 8718709 = 8718866
193 + 8718673 = 8718866

Showing the first eight; more decompositions exist.
