Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723456, here are decompositions:

19 + 8723437 = 8723456
37 + 8723419 = 8723456
97 + 8723359 = 8723456
103 + 8723353 = 8723456
109 + 8723347 = 8723456
139 + 8723317 = 8723456
307 + 8723149 = 8723456
349 + 8723107 = 8723456

Showing the first eight; more decompositions exist.
