Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591784, here are decompositions:

11 + 8591773 = 8591784
13 + 8591771 = 8591784
37 + 8591747 = 8591784
67 + 8591717 = 8591784
73 + 8591711 = 8591784
101 + 8591683 = 8591784
151 + 8591633 = 8591784
167 + 8591617 = 8591784

Showing the first eight; more decompositions exist.
