Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658244, here are decompositions:

11 + 8658233 = 8658244
41 + 8658203 = 8658244
83 + 8658161 = 8658244
107 + 8658137 = 8658244
137 + 8658107 = 8658244
227 + 8658017 = 8658244
311 + 8657933 = 8658244
317 + 8657927 = 8658244

Showing the first eight; more decompositions exist.
