Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19300, here are decompositions:

  • 11 + 19289 = 19300
  • 41 + 19259 = 19300
  • 89 + 19211 = 19300
  • 137 + 19163 = 19300
  • 179 + 19121 = 19300
  • 227 + 19073 = 19300
  • 263 + 19037 = 19300
  • 269 + 19031 = 19300

Showing the first eight; more decompositions exist.
