Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85828, here are decompositions:

  • 11 + 85817 = 85828
  • 47 + 85781 = 85828
  • 137 + 85691 = 85828
  • 167 + 85661 = 85828
  • 227 + 85601 = 85828
  • 251 + 85577 = 85828
  • 257 + 85571 = 85828
  • 311 + 85517 = 85828

Showing the first eight; more decompositions exist.
