Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18770, here are decompositions:

  • 13 + 18757 = 18770
  • 79 + 18691 = 18770
  • 109 + 18661 = 18770
  • 229 + 18541 = 18770
  • 277 + 18493 = 18770
  • 313 + 18457 = 18770
  • 331 + 18439 = 18770
  • 337 + 18433 = 18770

Showing the first eight; more decompositions exist.
