Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623140, here are decompositions:

17 + 8623123 = 8623140
37 + 8623103 = 8623140
59 + 8623081 = 8623140
67 + 8623073 = 8623140
73 + 8623067 = 8623140
79 + 8623061 = 8623140
89 + 8623051 = 8623140
101 + 8623039 = 8623140

Showing the first eight; more decompositions exist.
