Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639252, here are decompositions:

3 + 8639249 = 8639252
103 + 8639149 = 8639252
109 + 8639143 = 8639252
163 + 8639089 = 8639252
241 + 8639011 = 8639252
409 + 8638843 = 8639252
619 + 8638633 = 8639252
631 + 8638621 = 8639252

Showing the first eight; more decompositions exist.
