Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623522, here are decompositions:

3 + 8623519 = 8623522
113 + 8623409 = 8623522
269 + 8623253 = 8623522
419 + 8623103 = 8623522
449 + 8623073 = 8623522
461 + 8623061 = 8623522
491 + 8623031 = 8623522
503 + 8623019 = 8623522

Showing the first eight; more decompositions exist.
