Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623898, here are decompositions:

67 + 8623831 = 8623898
97 + 8623801 = 8623898
181 + 8623717 = 8623898
211 + 8623687 = 8623898
277 + 8623621 = 8623898
379 + 8623519 = 8623898
541 + 8623357 = 8623898
607 + 8623291 = 8623898

Showing the first eight; more decompositions exist.
