Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712400, here are decompositions:

  • 3 + 8712397 = 8712400
  • 29 + 8712371 = 8712400
  • 89 + 8712311 = 8712400
  • 107 + 8712293 = 8712400
  • 113 + 8712287 = 8712400
  • 131 + 8712269 = 8712400
  • 167 + 8712233 = 8712400
  • 173 + 8712227 = 8712400

Showing the first eight; more decompositions exist.
