Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712824, here are decompositions:

31 + 8712793 = 8712824
67 + 8712757 = 8712824
73 + 8712751 = 8712824
97 + 8712727 = 8712824
163 + 8712661 = 8712824
223 + 8712601 = 8712824
277 + 8712547 = 8712824
457 + 8712367 = 8712824

Showing the first eight; more decompositions exist.
