Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663824, here are decompositions:

3 + 8663821 = 8663824
5 + 8663819 = 8663824
17 + 8663807 = 8663824
47 + 8663777 = 8663824
83 + 8663741 = 8663824
137 + 8663687 = 8663824
317 + 8663507 = 8663824
353 + 8663471 = 8663824

Showing the first eight; more decompositions exist.
