Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172546, here are decompositions:

  • 5 + 172541 = 172546
  • 29 + 172517 = 172546
  • 107 + 172439 = 172546
  • 113 + 172433 = 172546
  • 173 + 172373 = 172546
  • 233 + 172313 = 172546
  • 239 + 172307 = 172546
  • 263 + 172283 = 172546

Showing the first eight; more decompositions exist.
