Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692420, here are decompositions:

3 + 8692417 = 8692420
17 + 8692403 = 8692420
89 + 8692331 = 8692420
101 + 8692319 = 8692420
131 + 8692289 = 8692420
137 + 8692283 = 8692420
197 + 8692223 = 8692420
239 + 8692181 = 8692420

Showing the first eight; more decompositions exist.
