Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611644, here are decompositions:

11 + 8611633 = 8611644
31 + 8611613 = 8611644
43 + 8611601 = 8611644
47 + 8611597 = 8611644
71 + 8611573 = 8611644
113 + 8611531 = 8611644
157 + 8611487 = 8611644
211 + 8611433 = 8611644

Showing the first eight; more decompositions exist.
