Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751378, here are decompositions:

7 + 8751371 = 8751378
11 + 8751367 = 8751378
29 + 8751349 = 8751378
37 + 8751341 = 8751378
59 + 8751319 = 8751378
89 + 8751289 = 8751378
127 + 8751251 = 8751378
157 + 8751221 = 8751378

Showing the first eight; more decompositions exist.
