Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526830, here are decompositions:

  • 11 + 31526819 = 31526830
  • 53 + 31526777 = 31526830
  • 59 + 31526771 = 31526830
  • 107 + 31526723 = 31526830
  • 197 + 31526633 = 31526830
  • 227 + 31526603 = 31526830
  • 353 + 31526477 = 31526830
  • 443 + 31526387 = 31526830

Showing the first eight; more decompositions exist.
