Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628144, here are decompositions:

13 + 8628131 = 8628144
23 + 8628121 = 8628144
37 + 8628107 = 8628144
47 + 8628097 = 8628144
67 + 8628077 = 8628144
113 + 8628031 = 8628144
127 + 8628017 = 8628144
137 + 8628007 = 8628144

Showing the first eight; more decompositions exist.
