Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43842, here are decompositions:

  • 41 + 43801 = 43842
  • 53 + 43789 = 43842
  • 59 + 43783 = 43842
  • 61 + 43781 = 43842
  • 83 + 43759 = 43842
  • 89 + 43753 = 43842
  • 131 + 43711 = 43842
  • 151 + 43691 = 43842

Showing the first eight; more decompositions exist.
