Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712278, here are decompositions:

  • 19 + 8712259 = 8712278
  • 97 + 8712181 = 8712278
  • 109 + 8712169 = 8712278
  • 307 + 8711971 = 8712278
  • 409 + 8711869 = 8712278
  • 457 + 8711821 = 8712278
  • 541 + 8711737 = 8712278
  • 571 + 8711707 = 8712278

Showing the first eight; more decompositions exist.
