Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526746, here are decompositions:

  • 23 + 31526723 = 31526746
  • 113 + 31526633 = 31526746
  • 257 + 31526489 = 31526746
  • 269 + 31526477 = 31526746
  • 359 + 31526387 = 31526746
  • 557 + 31526189 = 31526746
  • 659 + 31526087 = 31526746
  • 677 + 31526069 = 31526746

Showing the first eight; more decompositions exist.
