Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649170, here are decompositions:

67 + 8649103 = 8649170
109 + 8649061 = 8649170
241 + 8648929 = 8649170
307 + 8648863 = 8649170
331 + 8648839 = 8649170
337 + 8648833 = 8649170
373 + 8648797 = 8649170
379 + 8648791 = 8649170

Showing the first eight; more decompositions exist.
