Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655244, here are decompositions:

47 + 8655197 = 8655244
71 + 8655173 = 8655244
173 + 8655071 = 8655244
197 + 8655047 = 8655244
233 + 8655011 = 8655244
263 + 8654981 = 8655244
347 + 8654897 = 8655244
491 + 8654753 = 8655244

Showing the first eight; more decompositions exist.
