Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527126, here are decompositions:

  • 17 + 31527109 = 31527126
  • 19 + 31527107 = 31527126
  • 79 + 31527047 = 31527126
  • 109 + 31527017 = 31527126
  • 173 + 31526953 = 31527126
  • 199 + 31526927 = 31527126
  • 223 + 31526903 = 31527126
  • 227 + 31526899 = 31527126

Showing the first eight; more decompositions exist.
