Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712800, here are decompositions:

  • 7 + 8712793 = 8712800
  • 43 + 8712757 = 8712800
  • 73 + 8712727 = 8712800
  • 139 + 8712661 = 8712800
  • 199 + 8712601 = 8712800
  • 223 + 8712577 = 8712800
  • 277 + 8712523 = 8712800
  • 379 + 8712421 = 8712800

Showing the first eight; more decompositions exist.
