Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723956, here are decompositions:

5 + 8723951 = 8723956
23 + 8723933 = 8723956
47 + 8723909 = 8723956
53 + 8723903 = 8723956
149 + 8723807 = 8723956
167 + 8723789 = 8723956
317 + 8723639 = 8723956
347 + 8723609 = 8723956

Showing the first eight; more decompositions exist.
