Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649446, here are decompositions:

37 + 8649409 = 8649446
79 + 8649367 = 8649446
97 + 8649349 = 8649446
103 + 8649343 = 8649446
163 + 8649283 = 8649446
193 + 8649253 = 8649446
367 + 8649079 = 8649446
397 + 8649049 = 8649446

Showing the first eight; more decompositions exist.
