Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691290, here are decompositions:

43 + 8691247 = 8691290
61 + 8691229 = 8691290
67 + 8691223 = 8691290
79 + 8691211 = 8691290
103 + 8691187 = 8691290
163 + 8691127 = 8691290
199 + 8691091 = 8691290
271 + 8691019 = 8691290

Showing the first eight; more decompositions exist.
