Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623556, here are decompositions:

37 + 8623519 = 8623556
127 + 8623429 = 8623556
163 + 8623393 = 8623556
199 + 8623357 = 8623556
307 + 8623249 = 8623556
433 + 8623123 = 8623556
523 + 8623033 = 8623556
673 + 8622883 = 8623556

Showing the first eight; more decompositions exist.
