Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649064, here are decompositions:

3 + 8649061 = 8649064
41 + 8649023 = 8649064
197 + 8648867 = 8649064
227 + 8648837 = 8649064
233 + 8648831 = 8649064
251 + 8648813 = 8649064
317 + 8648747 = 8649064
521 + 8648543 = 8649064

Showing the first eight; more decompositions exist.
