Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647962, here are decompositions:

13 + 8647949 = 8647962
73 + 8647889 = 8647962
83 + 8647879 = 8647962
139 + 8647823 = 8647962
179 + 8647783 = 8647962
223 + 8647739 = 8647962
251 + 8647711 = 8647962
263 + 8647699 = 8647962

Showing the first eight; more decompositions exist.
