Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739866, here are decompositions:

43 + 8739823 = 8739866
97 + 8739769 = 8739866
127 + 8739739 = 8739866
193 + 8739673 = 8739866
199 + 8739667 = 8739866
229 + 8739637 = 8739866
283 + 8739583 = 8739866
337 + 8739529 = 8739866

Showing the first eight; more decompositions exist.
