Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527110, here are decompositions:

  • 3 + 31527107 = 31527110
  • 157 + 31526953 = 31527110
  • 211 + 31526899 = 31527110
  • 229 + 31526881 = 31527110
  • 337 + 31526773 = 31527110
  • 379 + 31526731 = 31527110
  • 397 + 31526713 = 31527110
  • 421 + 31526689 = 31527110

Showing the first eight; more decompositions exist.
