Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649244, here are decompositions:

3 + 8649241 = 8649244
5 + 8649239 = 8649244
17 + 8649227 = 8649244
47 + 8649197 = 8649244
53 + 8649191 = 8649244
173 + 8649071 = 8649244
431 + 8648813 = 8649244
503 + 8648741 = 8649244

Showing the first eight; more decompositions exist.
