Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77210, here are decompositions:

  • 19 + 77191 = 77210
  • 43 + 77167 = 77210
  • 73 + 77137 = 77210
  • 109 + 77101 = 77210
  • 163 + 77047 = 77210
  • 181 + 77029 = 77210
  • 193 + 77017 = 77210
  • 337 + 76873 = 77210

Showing the first eight; more decompositions exist.
