Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751426, here are decompositions:

59 + 8751367 = 8751426
97 + 8751329 = 8751426
107 + 8751319 = 8751426
137 + 8751289 = 8751426
193 + 8751233 = 8751426
269 + 8751157 = 8751426
283 + 8751143 = 8751426
337 + 8751089 = 8751426

Showing the first eight; more decompositions exist.
