Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723950, here are decompositions:

3 + 8723947 = 8723950
17 + 8723933 = 8723950
29 + 8723921 = 8723950
41 + 8723909 = 8723950
47 + 8723903 = 8723950
71 + 8723879 = 8723950
311 + 8723639 = 8723950
419 + 8723531 = 8723950

Showing the first eight; more decompositions exist.
