Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626884, here are decompositions:

  • 43 + 31626841 = 31626884
  • 97 + 31626787 = 31626884
  • 193 + 31626691 = 31626884
  • 277 + 31626607 = 31626884
  • 313 + 31626571 = 31626884
  • 337 + 31626547 = 31626884
  • 463 + 31626421 = 31626884
  • 547 + 31626337 = 31626884

Showing the first eight; more decompositions exist.
