Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739644, here are decompositions:

7 + 8739637 = 8739644
37 + 8739607 = 8739644
61 + 8739583 = 8739644
163 + 8739481 = 8739644
181 + 8739463 = 8739644
211 + 8739433 = 8739644
307 + 8739337 = 8739644
313 + 8739331 = 8739644

Showing the first eight; more decompositions exist.
