Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701824, here are decompositions:

  • 11 + 8701813 = 8701824
  • 13 + 8701811 = 8701824
  • 67 + 8701757 = 8701824
  • 83 + 8701741 = 8701824
  • 101 + 8701723 = 8701824
  • 167 + 8701657 = 8701824
  • 181 + 8701643 = 8701824
  • 193 + 8701631 = 8701824

Showing the first eight; more decompositions exist.
