Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645798, here are decompositions:

  • 37 + 8645761 = 8645798
  • 79 + 8645719 = 8645798
  • 151 + 8645647 = 8645798
  • 181 + 8645617 = 8645798
  • 211 + 8645587 = 8645798
  • 307 + 8645491 = 8645798
  • 349 + 8645449 = 8645798
  • 367 + 8645431 = 8645798

Showing the first eight; more decompositions exist.
