Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527142, here are decompositions:

  • 11 + 31527131 = 31527142
  • 131 + 31527011 = 31527142
  • 239 + 31526903 = 31527142
  • 263 + 31526879 = 31527142
  • 389 + 31526753 = 31527142
  • 419 + 31526723 = 31527142
  • 509 + 31526633 = 31527142
  • 653 + 31526489 = 31527142

Showing the first eight; more decompositions exist.
