Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598554, here are decompositions:

  • 11 + 31598543 = 31598554
  • 17 + 31598537 = 31598554
  • 41 + 31598513 = 31598554
  • 131 + 31598423 = 31598554
  • 137 + 31598417 = 31598554
  • 173 + 31598381 = 31598554
  • 191 + 31598363 = 31598554
  • 227 + 31598327 = 31598554

Showing the first eight; more decompositions exist.
