Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678220, here are decompositions:

7 + 8678213 = 8678220
17 + 8678203 = 8678220
41 + 8678179 = 8678220
59 + 8678161 = 8678220
71 + 8678149 = 8678220
73 + 8678147 = 8678220
79 + 8678141 = 8678220
107 + 8678113 = 8678220

Showing the first eight; more decompositions exist.
