Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166318, here are decompositions:

  • 17 + 166301 = 166318
  • 29 + 166289 = 166318
  • 59 + 166259 = 166318
  • 71 + 166247 = 166318
  • 149 + 166169 = 166318
  • 167 + 166151 = 166318
  • 431 + 165887 = 166318
  • 461 + 165857 = 166318

Showing the first eight; more decompositions exist.
