Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51400, here are decompositions:

  • 17 + 51383 = 51400
  • 53 + 51347 = 51400
  • 59 + 51341 = 51400
  • 71 + 51329 = 51400
  • 113 + 51287 = 51400
  • 137 + 51263 = 51400
  • 197 + 51203 = 51400
  • 263 + 51137 = 51400

Showing the first eight; more decompositions exist.
