Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526342, here are decompositions:

  • 61 + 31526281 = 31526342
  • 103 + 31526239 = 31526342
  • 151 + 31526191 = 31526342
  • 433 + 31525909 = 31526342
  • 439 + 31525903 = 31526342
  • 571 + 31525771 = 31526342
  • 619 + 31525723 = 31526342
  • 643 + 31525699 = 31526342

Showing the first eight; more decompositions exist.
