Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155266, here are decompositions:

  • 47 + 155219 = 155266
  • 113 + 155153 = 155266
  • 179 + 155087 = 155266
  • 197 + 155069 = 155266
  • 239 + 155027 = 155266
  • 257 + 155009 = 155266
  • 263 + 155003 = 155266
  • 383 + 154883 = 155266

Showing the first eight; more decompositions exist.
