Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611450, here are decompositions:

11 + 8611439 = 8611450
17 + 8611433 = 8611450
47 + 8611403 = 8611450
101 + 8611349 = 8611450
149 + 8611301 = 8611450
167 + 8611283 = 8611450
269 + 8611181 = 8611450
311 + 8611139 = 8611450

Showing the first eight; more decompositions exist.
