Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624988, here are decompositions:

7 + 8624981 = 8624988
59 + 8624929 = 8624988
67 + 8624921 = 8624988
101 + 8624887 = 8624988
107 + 8624881 = 8624988
167 + 8624821 = 8624988
181 + 8624807 = 8624988
271 + 8624717 = 8624988

Showing the first eight; more decompositions exist.
