Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628072, here are decompositions:

23 + 8628049 = 8628072
41 + 8628031 = 8628072
53 + 8628019 = 8628072
163 + 8627909 = 8628072
179 + 8627893 = 8628072
239 + 8627833 = 8628072
263 + 8627809 = 8628072
331 + 8627741 = 8628072

Showing the first eight; more decompositions exist.
