Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 236, here are decompositions:

  • 3 + 233 = 236
  • 7 + 229 = 236
  • 13 + 223 = 236
  • 37 + 199 = 236
  • 43 + 193 = 236
  • 73 + 163 = 236
  • 79 + 157 = 236
  • 97 + 139 = 236

Showing the first eight; more decompositions exist.
