Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658420, here are decompositions:

7 + 8658413 = 8658420
37 + 8658383 = 8658420
97 + 8658323 = 8658420
107 + 8658313 = 8658420
131 + 8658289 = 8658420
227 + 8658193 = 8658420
283 + 8658137 = 8658420
311 + 8658109 = 8658420

Showing the first eight; more decompositions exist.
