Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690784, here are decompositions:

17 + 8690767 = 8690784
43 + 8690741 = 8690784
71 + 8690713 = 8690784
101 + 8690683 = 8690784
107 + 8690677 = 8690784
173 + 8690611 = 8690784
181 + 8690603 = 8690784
191 + 8690593 = 8690784

Showing the first eight; more decompositions exist.
