Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71944, here are decompositions:

  • 3 + 71941 = 71944
  • 11 + 71933 = 71944
  • 83 + 71861 = 71944
  • 101 + 71843 = 71944
  • 107 + 71837 = 71944
  • 137 + 71807 = 71944
  • 167 + 71777 = 71944
  • 233 + 71711 = 71944

Showing the first eight; more decompositions exist.
