Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623128, here are decompositions:

5 + 8623123 = 8623128
47 + 8623081 = 8623128
61 + 8623067 = 8623128
67 + 8623061 = 8623128
89 + 8623039 = 8623128
97 + 8623031 = 8623128
109 + 8623019 = 8623128
251 + 8622877 = 8623128

Showing the first eight; more decompositions exist.
