Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707828, here are decompositions:

11 + 8707817 = 8707828
47 + 8707781 = 8707828
131 + 8707697 = 8707828
167 + 8707661 = 8707828
179 + 8707649 = 8707828
197 + 8707631 = 8707828
449 + 8707379 = 8707828
587 + 8707241 = 8707828

Showing the first eight; more decompositions exist.
