Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42358, here are decompositions:

  • 59 + 42299 = 42358
  • 101 + 42257 = 42358
  • 131 + 42227 = 42358
  • 137 + 42221 = 42358
  • 149 + 42209 = 42358
  • 179 + 42179 = 42358
  • 227 + 42131 = 42358
  • 257 + 42101 = 42358

Showing the first eight; more decompositions exist.
