Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723998, here are decompositions:

5 + 8723993 = 8723998
11 + 8723987 = 8723998
47 + 8723951 = 8723998
89 + 8723909 = 8723998
191 + 8723807 = 8723998
359 + 8723639 = 8723998
389 + 8723609 = 8723998
467 + 8723531 = 8723998

Showing the first eight; more decompositions exist.
