Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526894, here are decompositions:

  • 13 + 31526881 = 31526894
  • 31 + 31526863 = 31526894
  • 103 + 31526791 = 31526894
  • 163 + 31526731 = 31526894
  • 181 + 31526713 = 31526894
  • 277 + 31526617 = 31526894
  • 331 + 31526563 = 31526894
  • 367 + 31526527 = 31526894

Showing the first eight; more decompositions exist.
