Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75842, here are decompositions:

  • 61 + 75781 = 75842
  • 139 + 75703 = 75842
  • 163 + 75679 = 75842
  • 223 + 75619 = 75842
  • 271 + 75571 = 75842
  • 331 + 75511 = 75842
  • 439 + 75403 = 75842
  • 619 + 75223 = 75842

Showing the first eight; more decompositions exist.
