Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97840, here are decompositions:

  • 11 + 97829 = 97840
  • 53 + 97787 = 97840
  • 167 + 97673 = 97840
  • 191 + 97649 = 97840
  • 227 + 97613 = 97840
  • 233 + 97607 = 97840
  • 257 + 97583 = 97840
  • 263 + 97577 = 97840

Showing the first eight; more decompositions exist.
