Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675728, here are decompositions:

29 + 8675699 = 8675728
107 + 8675621 = 8675728
137 + 8675591 = 8675728
401 + 8675327 = 8675728
419 + 8675309 = 8675728
431 + 8675297 = 8675728
617 + 8675111 = 8675728
701 + 8675027 = 8675728

Showing the first eight; more decompositions exist.
