Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172298, here are decompositions:

  • 19 + 172279 = 172298
  • 79 + 172219 = 172298
  • 127 + 172171 = 172298
  • 151 + 172147 = 172298
  • 229 + 172069 = 172298
  • 271 + 172027 = 172298
  • 277 + 172021 = 172298
  • 409 + 171889 = 172298

Showing the first eight; more decompositions exist.
