Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723982, here are decompositions:

5 + 8723977 = 8723982
31 + 8723951 = 8723982
53 + 8723929 = 8723982
61 + 8723921 = 8723982
73 + 8723909 = 8723982
79 + 8723903 = 8723982
83 + 8723899 = 8723982
89 + 8723893 = 8723982

Showing the first eight; more decompositions exist.
