Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670788, here are decompositions:

  • 37 + 8670751 = 8670788
  • 79 + 8670709 = 8670788
  • 109 + 8670679 = 8670788
  • 151 + 8670637 = 8670788
  • 199 + 8670589 = 8670788
  • 229 + 8670559 = 8670788
  • 307 + 8670481 = 8670788
  • 337 + 8670451 = 8670788

Showing the first eight; more decompositions exist.
