Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678468, here are decompositions:

109 + 8678359 = 8678468
157 + 8678311 = 8678468
307 + 8678161 = 8678468
439 + 8678029 = 8678468
457 + 8678011 = 8678468
577 + 8677891 = 8678468
709 + 8677759 = 8678468
787 + 8677681 = 8678468

Showing the first eight; more decompositions exist.
