Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657244, here are decompositions:

5 + 8657239 = 8657244
7 + 8657237 = 8657244
23 + 8657221 = 8657244
83 + 8657161 = 8657244
191 + 8657053 = 8657244
223 + 8657021 = 8657244
227 + 8657017 = 8657244
311 + 8656933 = 8657244

Showing the first eight; more decompositions exist.
