Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723992, here are decompositions:

5 + 8723987 = 8723992
41 + 8723951 = 8723992
59 + 8723933 = 8723992
71 + 8723921 = 8723992
83 + 8723909 = 8723992
89 + 8723903 = 8723992
113 + 8723879 = 8723992
353 + 8723639 = 8723992

Showing the first eight; more decompositions exist.
