Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20162, here are decompositions:

  • 13 + 20149 = 20162
  • 19 + 20143 = 20162
  • 61 + 20101 = 20162
  • 73 + 20089 = 20162
  • 139 + 20023 = 20162
  • 151 + 20011 = 20162
  • 199 + 19963 = 20162
  • 271 + 19891 = 20162

Showing the first eight; more decompositions exist.
