Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723876, here are decompositions:

43 + 8723833 = 8723876
199 + 8723677 = 8723876
223 + 8723653 = 8723876
283 + 8723593 = 8723876
307 + 8723569 = 8723876
379 + 8723497 = 8723876
397 + 8723479 = 8723876
439 + 8723437 = 8723876

Showing the first eight; more decompositions exist.
