Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620306, here are decompositions:

17 + 8620289 = 8620306
29 + 8620277 = 8620306
47 + 8620259 = 8620306
89 + 8620217 = 8620306
173 + 8620133 = 8620306
197 + 8620109 = 8620306
257 + 8620049 = 8620306
263 + 8620043 = 8620306

Showing the first eight; more decompositions exist.
