Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536842, here are decompositions:

  • 13 + 31536829 = 31536842
  • 19 + 31536823 = 31536842
  • 109 + 31536733 = 31536842
  • 229 + 31536613 = 31536842
  • 313 + 31536529 = 31536842
  • 439 + 31536403 = 31536842
  • 619 + 31536223 = 31536842
  • 823 + 31536019 = 31536842

Showing the first eight; more decompositions exist.
