Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625144, here are decompositions:

13 + 8625131 = 8625144
23 + 8625121 = 8625144
53 + 8625091 = 8625144
61 + 8625083 = 8625144
67 + 8625077 = 8625144
71 + 8625073 = 8625144
131 + 8625013 = 8625144
137 + 8625007 = 8625144

Showing the first eight; more decompositions exist.
