Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708784, here are decompositions:

43 + 8708741 = 8708784
53 + 8708731 = 8708784
67 + 8708717 = 8708784
83 + 8708701 = 8708784
127 + 8708657 = 8708784
157 + 8708627 = 8708784
163 + 8708621 = 8708784
167 + 8708617 = 8708784

Showing the first eight; more decompositions exist.
