Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723618, here are decompositions:

67 + 8723551 = 8723618
97 + 8723521 = 8723618
139 + 8723479 = 8723618
181 + 8723437 = 8723618
199 + 8723419 = 8723618
271 + 8723347 = 8723618
307 + 8723311 = 8723618
571 + 8723047 = 8723618

Showing the first eight; more decompositions exist.
