Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723824, here are decompositions:

3 + 8723821 = 8723824
17 + 8723807 = 8723824
293 + 8723531 = 8723824
383 + 8723441 = 8723824
401 + 8723423 = 8723824
503 + 8723321 = 8723824
521 + 8723303 = 8723824
701 + 8723123 = 8723824

Showing the first eight; more decompositions exist.
