Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601620, here are decompositions:

109 + 8601511 = 8601620
163 + 8601457 = 8601620
199 + 8601421 = 8601620
229 + 8601391 = 8601620
277 + 8601343 = 8601620
331 + 8601289 = 8601620
367 + 8601253 = 8601620
457 + 8601163 = 8601620

Showing the first eight; more decompositions exist.
