Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15532, here are decompositions:

  • 5 + 15527 = 15532
  • 59 + 15473 = 15532
  • 71 + 15461 = 15532
  • 89 + 15443 = 15532
  • 131 + 15401 = 15532
  • 149 + 15383 = 15532
  • 173 + 15359 = 15532
  • 233 + 15299 = 15532

Showing the first eight; more decompositions exist.
