Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751486, here are decompositions:

17 + 8751469 = 8751486
19 + 8751467 = 8751486
47 + 8751439 = 8751486
59 + 8751427 = 8751486
137 + 8751349 = 8751486
157 + 8751329 = 8751486
167 + 8751319 = 8751486
197 + 8751289 = 8751486

Showing the first eight; more decompositions exist.
