Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611418, here are decompositions:

7 + 8611411 = 8611418
19 + 8611399 = 8611418
37 + 8611381 = 8611418
61 + 8611357 = 8611418
97 + 8611321 = 8611418
157 + 8611261 = 8611418
199 + 8611219 = 8611418
271 + 8611147 = 8611418

Showing the first eight; more decompositions exist.
