Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678042, here are decompositions:

3 + 8678039 = 8678042
13 + 8678029 = 8678042
31 + 8678011 = 8678042
151 + 8677891 = 8678042
271 + 8677771 = 8678042
283 + 8677759 = 8678042
379 + 8677663 = 8678042
643 + 8677399 = 8678042

Showing the first eight; more decompositions exist.
