Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712628, here are decompositions:

  • 17 + 8712611 = 8712628
  • 131 + 8712497 = 8712628
  • 137 + 8712491 = 8712628
  • 257 + 8712371 = 8712628
  • 317 + 8712311 = 8712628
  • 347 + 8712281 = 8712628
  • 359 + 8712269 = 8712628
  • 401 + 8712227 = 8712628

Showing the first eight; more decompositions exist.
