Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727784, here are decompositions:

5 + 8727779 = 8727784
11 + 8727773 = 8727784
17 + 8727767 = 8727784
53 + 8727731 = 8727784
83 + 8727701 = 8727784
173 + 8727611 = 8727784
353 + 8727431 = 8727784
467 + 8727317 = 8727784

Showing the first eight; more decompositions exist.
