Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623018, here are decompositions:

59 + 8622959 = 8623018
251 + 8622767 = 8623018
311 + 8622707 = 8623018
557 + 8622461 = 8623018
659 + 8622359 = 8623018
809 + 8622209 = 8623018
827 + 8622191 = 8623018
881 + 8622137 = 8623018

Showing the first eight; more decompositions exist.
