Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724166, here are decompositions:

5 + 8724161 = 8724166
23 + 8724143 = 8724166
173 + 8723993 = 8724166
179 + 8723987 = 8724166
233 + 8723933 = 8724166
257 + 8723909 = 8724166
263 + 8723903 = 8724166
359 + 8723807 = 8724166

Showing the first eight; more decompositions exist.
