Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649374, here are decompositions:

3 + 8649371 = 8649374
7 + 8649367 = 8649374
31 + 8649343 = 8649374
43 + 8649331 = 8649374
163 + 8649211 = 8649374
271 + 8649103 = 8649374
313 + 8649061 = 8649374
373 + 8649001 = 8649374

Showing the first eight; more decompositions exist.
