Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739858, here are decompositions:

7 + 8739851 = 8739858
31 + 8739827 = 8739858
37 + 8739821 = 8739858
47 + 8739811 = 8739858
89 + 8739769 = 8739858
109 + 8739749 = 8739858
137 + 8739721 = 8739858
191 + 8739667 = 8739858

Showing the first eight; more decompositions exist.
