Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628988, here are decompositions:

89 + 8628899 = 8628988
131 + 8628857 = 8628988
197 + 8628791 = 8628988
311 + 8628677 = 8628988
359 + 8628629 = 8628988
509 + 8628479 = 8628988
827 + 8628161 = 8628988
839 + 8628149 = 8628988

Showing the first eight; more decompositions exist.
