Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127126, here are decompositions:

  • 3 + 127123 = 127126
  • 23 + 127103 = 127126
  • 47 + 127079 = 127126
  • 89 + 127037 = 127126
  • 137 + 126989 = 127126
  • 269 + 126857 = 127126
  • 383 + 126743 = 127126
  • 443 + 126683 = 127126

Showing the first eight; more decompositions exist.
