Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628272, here are decompositions:

151 + 8628121 = 8628272
223 + 8628049 = 8628272
241 + 8628031 = 8628272
379 + 8627893 = 8628272
421 + 8627851 = 8628272
439 + 8627833 = 8628272
463 + 8627809 = 8628272
571 + 8627701 = 8628272

Showing the first eight; more decompositions exist.
