Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627824, here are decompositions:

11 + 8627813 = 8627824
17 + 8627807 = 8627824
47 + 8627777 = 8627824
83 + 8627741 = 8627824
131 + 8627693 = 8627824
197 + 8627627 = 8627824
251 + 8627573 = 8627824
263 + 8627561 = 8627824

Showing the first eight; more decompositions exist.
