Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723480, here are decompositions:

43 + 8723437 = 8723480
61 + 8723419 = 8723480
127 + 8723353 = 8723480
163 + 8723317 = 8723480
277 + 8723203 = 8723480
331 + 8723149 = 8723480
373 + 8723107 = 8723480
433 + 8723047 = 8723480

Showing the first eight; more decompositions exist.
