Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727824, here are decompositions:

67 + 8727757 = 8727824
97 + 8727727 = 8727824
151 + 8727673 = 8727824
181 + 8727643 = 8727824
223 + 8727601 = 8727824
241 + 8727583 = 8727824
331 + 8727493 = 8727824
373 + 8727451 = 8727824

Showing the first eight; more decompositions exist.
