Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646258, here are decompositions:

11 + 8646247 = 8646258
31 + 8646227 = 8646258
37 + 8646221 = 8646258
139 + 8646119 = 8646258
151 + 8646107 = 8646258
197 + 8646061 = 8646258
199 + 8646059 = 8646258
241 + 8646017 = 8646258

Showing the first eight; more decompositions exist.
