Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611420, here are decompositions:

17 + 8611403 = 8611420
71 + 8611349 = 8611420
89 + 8611331 = 8611420
113 + 8611307 = 8611420
137 + 8611283 = 8611420
173 + 8611247 = 8611420
239 + 8611181 = 8611420
269 + 8611151 = 8611420

Showing the first eight; more decompositions exist.
