Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646458, here are decompositions:

97 + 8646361 = 8646458
181 + 8646277 = 8646458
199 + 8646259 = 8646458
211 + 8646247 = 8646458
277 + 8646181 = 8646458
397 + 8646061 = 8646458
487 + 8645971 = 8646458
571 + 8645887 = 8646458

Showing the first eight; more decompositions exist.
