Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649404, here are decompositions:

13 + 8649391 = 8649404
37 + 8649367 = 8649404
61 + 8649343 = 8649404
73 + 8649331 = 8649404
151 + 8649253 = 8649404
163 + 8649241 = 8649404
193 + 8649211 = 8649404
523 + 8648881 = 8649404

Showing the first eight; more decompositions exist.
