Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611678, here are decompositions:

11 + 8611667 = 8611678
59 + 8611619 = 8611678
149 + 8611529 = 8611678
191 + 8611487 = 8611678
239 + 8611439 = 8611678
347 + 8611331 = 8611678
431 + 8611247 = 8611678
641 + 8611037 = 8611678

Showing the first eight; more decompositions exist.
