Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723360, here are decompositions:

7 + 8723353 = 8723360
13 + 8723347 = 8723360
43 + 8723317 = 8723360
157 + 8723203 = 8723360
211 + 8723149 = 8723360
223 + 8723137 = 8723360
271 + 8723089 = 8723360
307 + 8723053 = 8723360

Showing the first eight; more decompositions exist.
