Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646290, here are decompositions:

13 + 8646277 = 8646290
31 + 8646259 = 8646290
43 + 8646247 = 8646290
67 + 8646223 = 8646290
109 + 8646181 = 8646290
127 + 8646163 = 8646290
229 + 8646061 = 8646290
349 + 8645941 = 8646290

Showing the first eight; more decompositions exist.
