Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751518, here are decompositions:

67 + 8751451 = 8751518
79 + 8751439 = 8751518
151 + 8751367 = 8751518
199 + 8751319 = 8751518
229 + 8751289 = 8751518
337 + 8751181 = 8751518
367 + 8751151 = 8751518
379 + 8751139 = 8751518

Showing the first eight; more decompositions exist.
