Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611486, here are decompositions:

47 + 8611439 = 8611486
53 + 8611433 = 8611486
83 + 8611403 = 8611486
137 + 8611349 = 8611486
179 + 8611307 = 8611486
239 + 8611247 = 8611486
347 + 8611139 = 8611486
353 + 8611133 = 8611486

Showing the first eight; more decompositions exist.
