Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668480, here are decompositions:

  • 59 + 8668421 = 8668480
  • 101 + 8668379 = 8668480
  • 113 + 8668367 = 8668480
  • 131 + 8668349 = 8668480
  • 179 + 8668301 = 8668480
  • 347 + 8668133 = 8668480
  • 419 + 8668061 = 8668480
  • 449 + 8668031 = 8668480

Showing the first eight; more decompositions exist.
