Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668368, here are decompositions:

  • 11 + 8668357 = 8668368
  • 19 + 8668349 = 8668368
  • 67 + 8668301 = 8668368
  • 89 + 8668279 = 8668368
  • 101 + 8668267 = 8668368
  • 167 + 8668201 = 8668368
  • 211 + 8668157 = 8668368
  • 227 + 8668141 = 8668368

Showing the first eight; more decompositions exist.
