Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678668, here are decompositions:

29 + 8678639 = 8678668
149 + 8678519 = 8678668
269 + 8678399 = 8678668
431 + 8678237 = 8678668
521 + 8678147 = 8678668
587 + 8678081 = 8678668
599 + 8678069 = 8678668
617 + 8678051 = 8678668

Showing the first eight; more decompositions exist.
