Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84178, here are decompositions:

  • 41 + 84137 = 84178
  • 47 + 84131 = 84178
  • 89 + 84089 = 84178
  • 131 + 84047 = 84178
  • 167 + 84011 = 84178
  • 191 + 83987 = 84178
  • 239 + 83939 = 84178
  • 257 + 83921 = 84178

Showing the first eight; more decompositions exist.
