Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623530, here are decompositions:

7 + 8623523 = 8623530
11 + 8623519 = 8623530
101 + 8623429 = 8623530
107 + 8623423 = 8623530
137 + 8623393 = 8623530
173 + 8623357 = 8623530
191 + 8623339 = 8623530
211 + 8623319 = 8623530

Showing the first eight; more decompositions exist.
