Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157426, here are decompositions:

  • 149 + 157277 = 157426
  • 167 + 157259 = 157426
  • 173 + 157253 = 157426
  • 179 + 157247 = 157426
  • 197 + 157229 = 157426
  • 263 + 157163 = 157426
  • 293 + 157133 = 157426
  • 317 + 157109 = 157426

Showing the first eight; more decompositions exist.
