Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623528, here are decompositions:

5 + 8623523 = 8623528
281 + 8623247 = 8623528
461 + 8623067 = 8623528
467 + 8623061 = 8623528
491 + 8623037 = 8623528
509 + 8623019 = 8623528
569 + 8622959 = 8623528
761 + 8622767 = 8623528

Showing the first eight; more decompositions exist.
