Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618306, here are decompositions:

13 + 8618293 = 8618306
19 + 8618287 = 8618306
157 + 8618149 = 8618306
199 + 8618107 = 8618306
223 + 8618083 = 8618306
313 + 8617993 = 8618306
373 + 8617933 = 8618306
379 + 8617927 = 8618306

Showing the first eight; more decompositions exist.
