Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6442, here are decompositions:

  • 53 + 6389 = 6442
  • 83 + 6359 = 6442
  • 89 + 6353 = 6442
  • 113 + 6329 = 6442
  • 131 + 6311 = 6442
  • 173 + 6269 = 6442
  • 179 + 6263 = 6442
  • 239 + 6203 = 6442

Showing the first eight; more decompositions exist.
