Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17770, here are decompositions:

  • 23 + 17747 = 17770
  • 41 + 17729 = 17770
  • 89 + 17681 = 17770
  • 101 + 17669 = 17770
  • 113 + 17657 = 17770
  • 173 + 17597 = 17770
  • 191 + 17579 = 17770
  • 197 + 17573 = 17770

Showing the first eight; more decompositions exist.
