Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645472, here are decompositions:

23 + 8645449 = 8645472
29 + 8645443 = 8645472
41 + 8645431 = 8645472
113 + 8645359 = 8645472
131 + 8645341 = 8645472
179 + 8645293 = 8645472
191 + 8645281 = 8645472
211 + 8645261 = 8645472

Showing the first eight; more decompositions exist.
