Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724160, here are decompositions:

17 + 8724143 = 8724160
59 + 8724101 = 8724160
89 + 8724071 = 8724160
167 + 8723993 = 8724160
173 + 8723987 = 8724160
227 + 8723933 = 8724160
239 + 8723921 = 8724160
251 + 8723909 = 8724160

Showing the first eight; more decompositions exist.
