Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19400, here are decompositions:

  • 13 + 19387 = 19400
  • 19 + 19381 = 19400
  • 67 + 19333 = 19400
  • 127 + 19273 = 19400
  • 151 + 19249 = 19400
  • 163 + 19237 = 19400
  • 181 + 19219 = 19400
  • 193 + 19207 = 19400

Showing the first eight; more decompositions exist.
