Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611518, here are decompositions:

17 + 8611501 = 8611518
31 + 8611487 = 8611518
79 + 8611439 = 8611518
107 + 8611411 = 8611518
137 + 8611381 = 8611518
197 + 8611321 = 8611518
211 + 8611307 = 8611518
257 + 8611261 = 8611518

Showing the first eight; more decompositions exist.
