Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640244, here are decompositions:

3 + 8640241 = 8640244
23 + 8640221 = 8640244
47 + 8640197 = 8640244
83 + 8640161 = 8640244
227 + 8640017 = 8640244
257 + 8639987 = 8640244
293 + 8639951 = 8640244
491 + 8639753 = 8640244

Showing the first eight; more decompositions exist.
