Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51040, here are decompositions:

  • 47 + 50993 = 51040
  • 71 + 50969 = 51040
  • 83 + 50957 = 51040
  • 89 + 50951 = 51040
  • 131 + 50909 = 51040
  • 149 + 50891 = 51040
  • 167 + 50873 = 51040
  • 173 + 50867 = 51040

Showing the first eight; more decompositions exist.
