Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723394, here are decompositions:

7 + 8723387 = 8723394
41 + 8723353 = 8723394
47 + 8723347 = 8723394
73 + 8723321 = 8723394
83 + 8723311 = 8723394
151 + 8723243 = 8723394
181 + 8723213 = 8723394
191 + 8723203 = 8723394

Showing the first eight; more decompositions exist.
