Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702842, here are decompositions:

  • 3 + 8702839 = 8702842
  • 23 + 8702819 = 8702842
  • 89 + 8702753 = 8702842
  • 149 + 8702693 = 8702842
  • 179 + 8702663 = 8702842
  • 251 + 8702591 = 8702842
  • 353 + 8702489 = 8702842
  • 359 + 8702483 = 8702842

Showing the first eight; more decompositions exist.
