Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526984, here are decompositions:

  • 31 + 31526953 = 31526984
  • 43 + 31526941 = 31526984
  • 103 + 31526881 = 31526984
  • 193 + 31526791 = 31526984
  • 211 + 31526773 = 31526984
  • 271 + 31526713 = 31526984
  • 337 + 31526647 = 31526984
  • 367 + 31526617 = 31526984

Showing the first eight; more decompositions exist.
