Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751386, here are decompositions:

19 + 8751367 = 8751386
37 + 8751349 = 8751386
67 + 8751319 = 8751386
97 + 8751289 = 8751386
229 + 8751157 = 8751386
307 + 8751079 = 8751386
349 + 8751037 = 8751386
373 + 8751013 = 8751386

Showing the first eight; more decompositions exist.
