Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723836, here are decompositions:

3 + 8723833 = 8723836
29 + 8723807 = 8723836
47 + 8723789 = 8723836
197 + 8723639 = 8723836
227 + 8723609 = 8723836
353 + 8723483 = 8723836
449 + 8723387 = 8723836
593 + 8723243 = 8723836

Showing the first eight; more decompositions exist.
