Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623120, here are decompositions:

17 + 8623103 = 8623120
47 + 8623073 = 8623120
53 + 8623067 = 8623120
59 + 8623061 = 8623120
83 + 8623037 = 8623120
89 + 8623031 = 8623120
101 + 8623019 = 8623120
137 + 8622983 = 8623120

Showing the first eight; more decompositions exist.
