Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689218, here are decompositions:

  • 37 + 8689181 = 8689218
  • 89 + 8689129 = 8689218
  • 107 + 8689111 = 8689218
  • 149 + 8689069 = 8689218
  • 179 + 8689039 = 8689218
  • 227 + 8688991 = 8689218
  • 257 + 8688961 = 8689218
  • 389 + 8688829 = 8689218

Showing the first eight; more decompositions exist.
