Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697128, here are decompositions:

  • 31 + 8697097 = 8697128
  • 67 + 8697061 = 8697128
  • 79 + 8697049 = 8697128
  • 151 + 8696977 = 8697128
  • 211 + 8696917 = 8697128
  • 337 + 8696791 = 8697128
  • 367 + 8696761 = 8697128
  • 379 + 8696749 = 8697128

Showing the first eight; more decompositions exist.
