Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723424, here are decompositions:

5 + 8723419 = 8723424
37 + 8723387 = 8723424
71 + 8723353 = 8723424
103 + 8723321 = 8723424
107 + 8723317 = 8723424
113 + 8723311 = 8723424
181 + 8723243 = 8723424
211 + 8723213 = 8723424

Showing the first eight; more decompositions exist.
