Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719784, here are decompositions:

13 + 8719771 = 8719784
37 + 8719747 = 8719784
103 + 8719681 = 8719784
181 + 8719603 = 8719784
193 + 8719591 = 8719784
211 + 8719573 = 8719784
457 + 8719327 = 8719784
523 + 8719261 = 8719784

Showing the first eight; more decompositions exist.
