Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678228, here are decompositions:

67 + 8678161 = 8678228
79 + 8678149 = 8678228
199 + 8678029 = 8678228
277 + 8677951 = 8678228
337 + 8677891 = 8678228
457 + 8677771 = 8678228
547 + 8677681 = 8678228
577 + 8677651 = 8678228

Showing the first eight; more decompositions exist.
