Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678222, here are decompositions:

19 + 8678203 = 8678222
43 + 8678179 = 8678222
61 + 8678161 = 8678222
73 + 8678149 = 8678222
109 + 8678113 = 8678222
139 + 8678083 = 8678222
193 + 8678029 = 8678222
211 + 8678011 = 8678222

Showing the first eight; more decompositions exist.
