Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42210, here are decompositions:

  • 13 + 42197 = 42210
  • 17 + 42193 = 42210
  • 23 + 42187 = 42210
  • 29 + 42181 = 42210
  • 31 + 42179 = 42210
  • 41 + 42169 = 42210
  • 53 + 42157 = 42210
  • 71 + 42139 = 42210

Showing the first eight; more decompositions exist.
