Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723648, here are decompositions:

79 + 8723569 = 8723648
97 + 8723551 = 8723648
127 + 8723521 = 8723648
151 + 8723497 = 8723648
211 + 8723437 = 8723648
229 + 8723419 = 8723648
331 + 8723317 = 8723648
337 + 8723311 = 8723648

Showing the first eight; more decompositions exist.
