Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612320, here are decompositions:

263 + 8612057 = 8612320
281 + 8612039 = 8612320
359 + 8611961 = 8612320
461 + 8611859 = 8612320
491 + 8611829 = 8612320
599 + 8611721 = 8612320
617 + 8611703 = 8612320
641 + 8611679 = 8612320

Showing the first eight; more decompositions exist.
