Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678920, here are decompositions:

17 + 8678903 = 8678920
137 + 8678783 = 8678920
167 + 8678753 = 8678920
179 + 8678741 = 8678920
227 + 8678693 = 8678920
251 + 8678669 = 8678920
281 + 8678639 = 8678920
317 + 8678603 = 8678920

Showing the first eight; more decompositions exist.
