Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606420, here are decompositions:

7 + 8606413 = 8606420
19 + 8606401 = 8606420
79 + 8606341 = 8606420
127 + 8606293 = 8606420
139 + 8606281 = 8606420
157 + 8606263 = 8606420
223 + 8606197 = 8606420
241 + 8606179 = 8606420

Showing the first eight; more decompositions exist.
