Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612668, here are decompositions:

5 + 8612663 = 8612668
11 + 8612657 = 8612668
41 + 8612627 = 8612668
137 + 8612531 = 8612668
257 + 8612411 = 8612668
269 + 8612399 = 8612668
569 + 8612099 = 8612668
677 + 8611991 = 8612668

Showing the first eight; more decompositions exist.
