Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645484, here are decompositions:

7 + 8645477 = 8645484
41 + 8645443 = 8645484
53 + 8645431 = 8645484
103 + 8645381 = 8645484
131 + 8645353 = 8645484
157 + 8645327 = 8645484
191 + 8645293 = 8645484
223 + 8645261 = 8645484

Showing the first eight; more decompositions exist.
