Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612398, here are decompositions:

359 + 8612039 = 8612398
569 + 8611829 = 8612398
677 + 8611721 = 8612398
701 + 8611697 = 8612398
719 + 8611679 = 8612398
797 + 8611601 = 8612398
911 + 8611487 = 8612398
1049 + 8611349 = 8612398

Showing the first eight; more decompositions exist.
