Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751438, here are decompositions:

11 + 8751427 = 8751438
37 + 8751401 = 8751438
67 + 8751371 = 8751438
71 + 8751367 = 8751438
89 + 8751349 = 8751438
97 + 8751341 = 8751438
109 + 8751329 = 8751438
149 + 8751289 = 8751438

Showing the first eight; more decompositions exist.
