Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523442, here are decompositions:

  • 109 + 523333 = 523442
  • 181 + 523261 = 523442
  • 223 + 523219 = 523442
  • 229 + 523213 = 523442
  • 313 + 523129 = 523442
  • 349 + 523093 = 523442
  • 421 + 523021 = 523442
  • 499 + 522943 = 523442

Showing the first eight; more decompositions exist.
