Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696420, here are decompositions:

13 + 8696407 = 8696420
37 + 8696383 = 8696420
43 + 8696377 = 8696420
157 + 8696263 = 8696420
181 + 8696239 = 8696420
193 + 8696227 = 8696420
211 + 8696209 = 8696420
241 + 8696179 = 8696420

Showing the first eight; more decompositions exist.
