Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612620, here are decompositions:

89 + 8612531 = 8612620
197 + 8612423 = 8612620
521 + 8612099 = 8612620
563 + 8612057 = 8612620
587 + 8612033 = 8612620
659 + 8611961 = 8612620
761 + 8611859 = 8612620
773 + 8611847 = 8612620

Showing the first eight; more decompositions exist.
