Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676428, here are decompositions:

31 + 8676397 = 8676428
67 + 8676361 = 8676428
109 + 8676319 = 8676428
127 + 8676301 = 8676428
199 + 8676229 = 8676428
349 + 8676079 = 8676428
367 + 8676061 = 8676428
379 + 8676049 = 8676428

Showing the first eight; more decompositions exist.
