Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649524, here are decompositions:

3 + 8649521 = 8649524
7 + 8649517 = 8649524
61 + 8649463 = 8649524
73 + 8649451 = 8649524
157 + 8649367 = 8649524
181 + 8649343 = 8649524
193 + 8649331 = 8649524
241 + 8649283 = 8649524

Showing the first eight; more decompositions exist.
