Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658980, here are decompositions:

3 + 8658977 = 8658980
19 + 8658961 = 8658980
37 + 8658943 = 8658980
61 + 8658919 = 8658980
103 + 8658877 = 8658980
151 + 8658829 = 8658980
223 + 8658757 = 8658980
241 + 8658739 = 8658980

Showing the first eight; more decompositions exist.
