Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526486, here are decompositions:

  • 67 + 31526419 = 31526486
  • 97 + 31526389 = 31526486
  • 127 + 31526359 = 31526486
  • 577 + 31525909 = 31526486
  • 709 + 31525777 = 31526486
  • 769 + 31525717 = 31526486
  • 787 + 31525699 = 31526486
  • 829 + 31525657 = 31526486

Showing the first eight; more decompositions exist.
