Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668290, here are decompositions:

  • 11 + 8668279 = 8668290
  • 17 + 8668273 = 8668290
  • 23 + 8668267 = 8668290
  • 83 + 8668207 = 8668290
  • 89 + 8668201 = 8668290
  • 97 + 8668193 = 8668290
  • 139 + 8668151 = 8668290
  • 149 + 8668141 = 8668290

Showing the first eight; more decompositions exist.
