Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678240, here are decompositions:

3 + 8678237 = 8678240
37 + 8678203 = 8678240
61 + 8678179 = 8678240
79 + 8678161 = 8678240
127 + 8678113 = 8678240
157 + 8678083 = 8678240
211 + 8678029 = 8678240
229 + 8678011 = 8678240

Showing the first eight; more decompositions exist.
