Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616980, here are decompositions:

61 + 8616919 = 8616980
67 + 8616913 = 8616980
79 + 8616901 = 8616980
199 + 8616781 = 8616980
223 + 8616757 = 8616980
277 + 8616703 = 8616980
433 + 8616547 = 8616980
439 + 8616541 = 8616980

Showing the first eight; more decompositions exist.
