Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526722, here are decompositions:

  • 53 + 31526669 = 31526722
  • 89 + 31526633 = 31526722
  • 233 + 31526489 = 31526722
  • 449 + 31526273 = 31526722
  • 509 + 31526213 = 31526722
  • 653 + 31526069 = 31526722
  • 659 + 31526063 = 31526722
  • 701 + 31526021 = 31526722

Showing the first eight; more decompositions exist.
