Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739918, here are decompositions:

7 + 8739911 = 8739918
17 + 8739901 = 8739918
41 + 8739877 = 8739918
67 + 8739851 = 8739918
97 + 8739821 = 8739918
107 + 8739811 = 8739918
149 + 8739769 = 8739918
151 + 8739767 = 8739918

Showing the first eight; more decompositions exist.
