Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611356, here are decompositions:

7 + 8611349 = 8611356
53 + 8611303 = 8611356
59 + 8611297 = 8611356
73 + 8611283 = 8611356
107 + 8611249 = 8611356
109 + 8611247 = 8611356
137 + 8611219 = 8611356
223 + 8611133 = 8611356

Showing the first eight; more decompositions exist.
