Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720048, here are decompositions:

  • 61 + 8719987 = 8720048
  • 97 + 8719951 = 8720048
  • 109 + 8719939 = 8720048
  • 229 + 8719819 = 8720048
  • 277 + 8719771 = 8720048
  • 349 + 8719699 = 8720048
  • 367 + 8719681 = 8720048
  • 457 + 8719591 = 8720048

Showing the first eight; more decompositions exist.
