Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721704, here are decompositions:

3 + 8721701 = 8721704
31 + 8721673 = 8721704
37 + 8721667 = 8721704
73 + 8721631 = 8721704
97 + 8721607 = 8721704
163 + 8721541 = 8721704
193 + 8721511 = 8721704
223 + 8721481 = 8721704

Showing the first eight; more decompositions exist.
