Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739620, here are decompositions:

3 + 8739617 = 8739620
13 + 8739607 = 8739620
37 + 8739583 = 8739620
139 + 8739481 = 8739620
157 + 8739463 = 8739620
223 + 8739397 = 8739620
229 + 8739391 = 8739620
271 + 8739349 = 8739620

Showing the first eight; more decompositions exist.
