Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723566, here are decompositions:

83 + 8723483 = 8723566
107 + 8723459 = 8723566
167 + 8723399 = 8723566
179 + 8723387 = 8723566
263 + 8723303 = 8723566
353 + 8723213 = 8723566
443 + 8723123 = 8723566
503 + 8723063 = 8723566

Showing the first eight; more decompositions exist.
