Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678190, here are decompositions:

11 + 8678179 = 8678190
29 + 8678161 = 8678190
41 + 8678149 = 8678190
43 + 8678147 = 8678190
61 + 8678129 = 8678190
97 + 8678093 = 8678190
107 + 8678083 = 8678190
109 + 8678081 = 8678190

Showing the first eight; more decompositions exist.
