Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174538, here are decompositions:

  • 5 + 174533 = 174538
  • 11 + 174527 = 174538
  • 47 + 174491 = 174538
  • 71 + 174467 = 174538
  • 107 + 174431 = 174538
  • 131 + 174407 = 174538
  • 149 + 174389 = 174538
  • 191 + 174347 = 174538

Showing the first eight; more decompositions exist.
