Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723980, here are decompositions:

3 + 8723977 = 8723980
29 + 8723951 = 8723980
47 + 8723933 = 8723980
59 + 8723921 = 8723980
71 + 8723909 = 8723980
101 + 8723879 = 8723980
173 + 8723807 = 8723980
191 + 8723789 = 8723980

Showing the first eight; more decompositions exist.
