Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647782, here are decompositions:

23 + 8647759 = 8647782
29 + 8647753 = 8647782
43 + 8647739 = 8647782
71 + 8647711 = 8647782
83 + 8647699 = 8647782
193 + 8647589 = 8647782
251 + 8647531 = 8647782
271 + 8647511 = 8647782

Showing the first eight; more decompositions exist.
