Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736784, here are decompositions:

3 + 8736781 = 8736784
83 + 8736701 = 8736784
101 + 8736683 = 8736784
131 + 8736653 = 8736784
137 + 8736647 = 8736784
167 + 8736617 = 8736784
191 + 8736593 = 8736784
281 + 8736503 = 8736784

Showing the first eight; more decompositions exist.
