Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693420, here are decompositions:

13 + 8693407 = 8693420
19 + 8693401 = 8693420
97 + 8693323 = 8693420
139 + 8693281 = 8693420
157 + 8693263 = 8693420
163 + 8693257 = 8693420
193 + 8693227 = 8693420
223 + 8693197 = 8693420

Showing the first eight; more decompositions exist.
