Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611456, here are decompositions:

17 + 8611439 = 8611456
23 + 8611433 = 8611456
53 + 8611403 = 8611456
107 + 8611349 = 8611456
149 + 8611307 = 8611456
173 + 8611283 = 8611456
317 + 8611139 = 8611456
419 + 8611037 = 8611456

Showing the first eight; more decompositions exist.
