Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723892, here are decompositions:

5 + 8723887 = 8723892
13 + 8723879 = 8723892
41 + 8723851 = 8723892
59 + 8723833 = 8723892
71 + 8723821 = 8723892
103 + 8723789 = 8723892
239 + 8723653 = 8723892
283 + 8723609 = 8723892

Showing the first eight; more decompositions exist.
