Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655784, here are decompositions:

23 + 8655761 = 8655784
83 + 8655701 = 8655784
107 + 8655677 = 8655784
113 + 8655671 = 8655784
131 + 8655653 = 8655784
173 + 8655611 = 8655784
257 + 8655527 = 8655784
383 + 8655401 = 8655784

Showing the first eight; more decompositions exist.
