Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526938, here are decompositions:

  • 11 + 31526927 = 31526938
  • 17 + 31526921 = 31526938
  • 59 + 31526879 = 31526938
  • 167 + 31526771 = 31526938
  • 269 + 31526669 = 31526938
  • 449 + 31526489 = 31526938
  • 461 + 31526477 = 31526938
  • 587 + 31526351 = 31526938

Showing the first eight; more decompositions exist.
