Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678180, here are decompositions:

19 + 8678161 = 8678180
31 + 8678149 = 8678180
67 + 8678113 = 8678180
97 + 8678083 = 8678180
127 + 8678053 = 8678180
151 + 8678029 = 8678180
229 + 8677951 = 8678180
409 + 8677771 = 8678180

Showing the first eight; more decompositions exist.
