Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667388, here are decompositions:

  • 11 + 8667377 = 8667388
  • 17 + 8667371 = 8667388
  • 89 + 8667299 = 8667388
  • 131 + 8667257 = 8667388
  • 251 + 8667137 = 8667388
  • 449 + 8666939 = 8667388
  • 461 + 8666927 = 8667388
  • 641 + 8666747 = 8667388

Showing the first eight; more decompositions exist.
