Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702824, here are decompositions:

3 + 8702821 = 8702824
5 + 8702819 = 8702824
47 + 8702777 = 8702824
71 + 8702753 = 8702824
131 + 8702693 = 8702824
227 + 8702597 = 8702824
233 + 8702591 = 8702824
281 + 8702543 = 8702824

Showing the first eight; more decompositions exist.
