Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56172, here are decompositions:

  • 5 + 56167 = 56172
  • 23 + 56149 = 56172
  • 41 + 56131 = 56172
  • 59 + 56113 = 56172
  • 71 + 56101 = 56172
  • 73 + 56099 = 56172
  • 79 + 56093 = 56172
  • 131 + 56041 = 56172

Showing the first eight; more decompositions exist.
