Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526798, here are decompositions:

  • 7 + 31526791 = 31526798
  • 67 + 31526731 = 31526798
  • 109 + 31526689 = 31526798
  • 151 + 31526647 = 31526798
  • 181 + 31526617 = 31526798
  • 271 + 31526527 = 31526798
  • 367 + 31526431 = 31526798
  • 379 + 31526419 = 31526798

Showing the first eight; more decompositions exist.
