Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616620, here are decompositions:

73 + 8616547 = 8616620
79 + 8616541 = 8616620
127 + 8616493 = 8616620
163 + 8616457 = 8616620
223 + 8616397 = 8616620
241 + 8616379 = 8616620
283 + 8616337 = 8616620
349 + 8616271 = 8616620

Showing the first eight; more decompositions exist.
