Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623020, here are decompositions:

17 + 8623003 = 8623020
37 + 8622983 = 8623020
47 + 8622973 = 8623020
61 + 8622959 = 8623020
97 + 8622923 = 8623020
137 + 8622883 = 8623020
149 + 8622871 = 8623020
163 + 8622857 = 8623020

Showing the first eight; more decompositions exist.
