Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649320, here are decompositions:

3 + 8649317 = 8649320
37 + 8649283 = 8649320
67 + 8649253 = 8649320
79 + 8649241 = 8649320
109 + 8649211 = 8649320
241 + 8649079 = 8649320
271 + 8649049 = 8649320
367 + 8648953 = 8649320

Showing the first eight; more decompositions exist.
