Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723984, here are decompositions:

7 + 8723977 = 8723984
37 + 8723947 = 8723984
97 + 8723887 = 8723984
151 + 8723833 = 8723984
163 + 8723821 = 8723984
277 + 8723707 = 8723984
307 + 8723677 = 8723984
331 + 8723653 = 8723984

Showing the first eight; more decompositions exist.
