Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526858, here are decompositions:

  • 67 + 31526791 = 31526858
  • 109 + 31526749 = 31526858
  • 127 + 31526731 = 31526858
  • 211 + 31526647 = 31526858
  • 241 + 31526617 = 31526858
  • 331 + 31526527 = 31526858
  • 439 + 31526419 = 31526858
  • 487 + 31526371 = 31526858

Showing the first eight; more decompositions exist.
