Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623826, here are decompositions:

19 + 8623807 = 8623826
97 + 8623729 = 8623826
109 + 8623717 = 8623826
139 + 8623687 = 8623826
223 + 8623603 = 8623826
307 + 8623519 = 8623826
397 + 8623429 = 8623826
433 + 8623393 = 8623826

Showing the first eight; more decompositions exist.
