Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645738, here are decompositions:

19 + 8645719 = 8645738
151 + 8645587 = 8645738
307 + 8645431 = 8645738
331 + 8645407 = 8645738
379 + 8645359 = 8645738
397 + 8645341 = 8645738
457 + 8645281 = 8645738
499 + 8645239 = 8645738

Showing the first eight; more decompositions exist.
