Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739786, here are decompositions:

17 + 8739769 = 8739786
19 + 8739767 = 8739786
37 + 8739749 = 8739786
47 + 8739739 = 8739786
73 + 8739713 = 8739786
113 + 8739673 = 8739786
149 + 8739637 = 8739786
163 + 8739623 = 8739786

Showing the first eight; more decompositions exist.
