Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127188, here are decompositions:

  • 31 + 127157 = 127188
  • 107 + 127081 = 127188
  • 109 + 127079 = 127188
  • 137 + 127051 = 127188
  • 151 + 127037 = 127188
  • 157 + 127031 = 127188
  • 199 + 126989 = 127188
  • 227 + 126961 = 127188

Showing the first eight; more decompositions exist.
