Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739836, here are decompositions:

13 + 8739823 = 8739836
67 + 8739769 = 8739836
97 + 8739739 = 8739836
163 + 8739673 = 8739836
199 + 8739637 = 8739836
229 + 8739607 = 8739836
307 + 8739529 = 8739836
337 + 8739499 = 8739836

Showing the first eight; more decompositions exist.
