Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611436, here are decompositions:

3 + 8611433 = 8611436
13 + 8611423 = 8611436
37 + 8611399 = 8611436
79 + 8611357 = 8611436
139 + 8611297 = 8611436
373 + 8611063 = 8611436
433 + 8611003 = 8611436
439 + 8610997 = 8611436

Showing the first eight; more decompositions exist.
