Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697784, here are decompositions:

5 + 8697779 = 8697784
101 + 8697683 = 8697784
107 + 8697677 = 8697784
197 + 8697587 = 8697784
233 + 8697551 = 8697784
281 + 8697503 = 8697784
521 + 8697263 = 8697784
677 + 8697107 = 8697784

Showing the first eight; more decompositions exist.
