Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707620, here are decompositions:

13 + 8707607 = 8707620
17 + 8707603 = 8707620
29 + 8707591 = 8707620
41 + 8707579 = 8707620
83 + 8707537 = 8707620
191 + 8707429 = 8707620
199 + 8707421 = 8707620
227 + 8707393 = 8707620

Showing the first eight; more decompositions exist.
