Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619420, here are decompositions:

23 + 8619397 = 8619420
67 + 8619353 = 8619420
151 + 8619269 = 8619420
157 + 8619263 = 8619420
179 + 8619241 = 8619420
191 + 8619229 = 8619420
197 + 8619223 = 8619420
223 + 8619197 = 8619420

Showing the first eight; more decompositions exist.
