Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678942, here are decompositions:

3 + 8678939 = 8678942
43 + 8678899 = 8678942
79 + 8678863 = 8678942
109 + 8678833 = 8678942
163 + 8678779 = 8678942
193 + 8678749 = 8678942
229 + 8678713 = 8678942
241 + 8678701 = 8678942

Showing the first eight; more decompositions exist.
