Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671420, here are decompositions:

11 + 8671409 = 8671420
53 + 8671367 = 8671420
59 + 8671361 = 8671420
89 + 8671331 = 8671420
113 + 8671307 = 8671420
227 + 8671193 = 8671420
269 + 8671151 = 8671420
293 + 8671127 = 8671420

Showing the first eight; more decompositions exist.
