Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751646, here are decompositions:

17 + 8751629 = 8751646
47 + 8751599 = 8751646
53 + 8751593 = 8751646
83 + 8751563 = 8751646
89 + 8751557 = 8751646
179 + 8751467 = 8751646
317 + 8751329 = 8751646
389 + 8751257 = 8751646

Showing the first eight; more decompositions exist.
