Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97780, here are decompositions:

  • 3 + 97777 = 97780
  • 107 + 97673 = 97780
  • 131 + 97649 = 97780
  • 167 + 97613 = 97780
  • 173 + 97607 = 97780
  • 197 + 97583 = 97780
  • 227 + 97553 = 97780
  • 233 + 97547 = 97780

Showing the first eight; more decompositions exist.
