Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751408, here are decompositions:

7 + 8751401 = 8751408
37 + 8751371 = 8751408
41 + 8751367 = 8751408
59 + 8751349 = 8751408
67 + 8751341 = 8751408
79 + 8751329 = 8751408
89 + 8751319 = 8751408
151 + 8751257 = 8751408

Showing the first eight; more decompositions exist.
