Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623980, here are decompositions:

11 + 8623969 = 8623980
17 + 8623963 = 8623980
19 + 8623961 = 8623980
41 + 8623939 = 8623980
83 + 8623897 = 8623980
97 + 8623883 = 8623980
137 + 8623843 = 8623980
149 + 8623831 = 8623980

Showing the first eight; more decompositions exist.
