Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628160, here are decompositions:

3 + 8628157 = 8628160
11 + 8628149 = 8628160
29 + 8628131 = 8628160
53 + 8628107 = 8628160
83 + 8628077 = 8628160
173 + 8627987 = 8628160
251 + 8627909 = 8628160
257 + 8627903 = 8628160

Showing the first eight; more decompositions exist.
