Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724216, here are decompositions:

47 + 8724169 = 8724216
73 + 8724143 = 8724216
89 + 8724127 = 8724216
223 + 8723993 = 8724216
229 + 8723987 = 8724216
239 + 8723977 = 8724216
269 + 8723947 = 8724216
283 + 8723933 = 8724216

Showing the first eight; more decompositions exist.
