Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5408, here are decompositions:

  • 61 + 5347 = 5408
  • 127 + 5281 = 5408
  • 181 + 5227 = 5408
  • 199 + 5209 = 5408
  • 211 + 5197 = 5408
  • 229 + 5179 = 5408
  • 241 + 5167 = 5408
  • 307 + 5101 = 5408

Showing the first eight; more decompositions exist.
