Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527124, here are decompositions:

  • 17 + 31527107 = 31527124
  • 47 + 31527077 = 31527124
  • 107 + 31527017 = 31527124
  • 113 + 31527011 = 31527124
  • 197 + 31526927 = 31527124
  • 347 + 31526777 = 31527124
  • 353 + 31526771 = 31527124
  • 401 + 31526723 = 31527124

Showing the first eight; more decompositions exist.
