Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55858, here are decompositions:

  • 29 + 55829 = 55858
  • 41 + 55817 = 55858
  • 59 + 55799 = 55858
  • 71 + 55787 = 55858
  • 137 + 55721 = 55858
  • 167 + 55691 = 55858
  • 191 + 55667 = 55858
  • 197 + 55661 = 55858

Showing the first eight; more decompositions exist.
