Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724214, here are decompositions:

53 + 8724161 = 8724214
71 + 8724143 = 8724214
113 + 8724101 = 8724214
227 + 8723987 = 8724214
263 + 8723951 = 8724214
281 + 8723933 = 8724214
293 + 8723921 = 8724214
311 + 8723903 = 8724214

Showing the first eight; more decompositions exist.
