Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670402, here are decompositions:

  • 5 + 8670397 = 8670402
  • 29 + 8670373 = 8670402
  • 31 + 8670371 = 8670402
  • 71 + 8670331 = 8670402
  • 89 + 8670313 = 8670402
  • 101 + 8670301 = 8670402
  • 163 + 8670239 = 8670402
  • 211 + 8670191 = 8670402

Showing the first eight; more decompositions exist.
