Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77330, here are decompositions:

  • 7 + 77323 = 77330
  • 13 + 77317 = 77330
  • 61 + 77269 = 77330
  • 67 + 77263 = 77330
  • 139 + 77191 = 77330
  • 163 + 77167 = 77330
  • 193 + 77137 = 77330
  • 229 + 77101 = 77330

Showing the first eight; more decompositions exist.
