Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623648, here are decompositions:

29 + 8623619 = 8623648
101 + 8623547 = 8623648
239 + 8623409 = 8623648
401 + 8623247 = 8623648
587 + 8623061 = 8623648
617 + 8623031 = 8623648
881 + 8622767 = 8623648
941 + 8622707 = 8623648

Showing the first eight; more decompositions exist.
