Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71842, here are decompositions:

  • 5 + 71837 = 71842
  • 53 + 71789 = 71842
  • 101 + 71741 = 71842
  • 131 + 71711 = 71842
  • 149 + 71693 = 71842
  • 179 + 71663 = 71842
  • 293 + 71549 = 71842
  • 359 + 71483 = 71842

Showing the first eight; more decompositions exist.
