Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678658, here are decompositions:

19 + 8678639 = 8678658
59 + 8678599 = 8678658
71 + 8678587 = 8678658
101 + 8678557 = 8678658
139 + 8678519 = 8678658
151 + 8678507 = 8678658
211 + 8678447 = 8678658
347 + 8678311 = 8678658

Showing the first eight; more decompositions exist.
