Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723850, here are decompositions:

17 + 8723833 = 8723850
29 + 8723821 = 8723850
43 + 8723807 = 8723850
61 + 8723789 = 8723850
173 + 8723677 = 8723850
197 + 8723653 = 8723850
211 + 8723639 = 8723850
241 + 8723609 = 8723850

Showing the first eight; more decompositions exist.
