Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723340, here are decompositions:

19 + 8723321 = 8723340
23 + 8723317 = 8723340
29 + 8723311 = 8723340
37 + 8723303 = 8723340
97 + 8723243 = 8723340
127 + 8723213 = 8723340
137 + 8723203 = 8723340
149 + 8723191 = 8723340

Showing the first eight; more decompositions exist.
