Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629888, here are decompositions:

5 + 8629883 = 8629888
41 + 8629847 = 8629888
149 + 8629739 = 8629888
227 + 8629661 = 8629888
251 + 8629637 = 8629888
479 + 8629409 = 8629888
647 + 8629241 = 8629888
719 + 8629169 = 8629888

Showing the first eight; more decompositions exist.
