Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611470, here are decompositions:

29 + 8611441 = 8611470
31 + 8611439 = 8611470
37 + 8611433 = 8611470
47 + 8611423 = 8611470
59 + 8611411 = 8611470
67 + 8611403 = 8611470
71 + 8611399 = 8611470
89 + 8611381 = 8611470

Showing the first eight; more decompositions exist.
