Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18370, here are decompositions:

  • 3 + 18367 = 18370
  • 17 + 18353 = 18370
  • 29 + 18341 = 18370
  • 41 + 18329 = 18370
  • 59 + 18311 = 18370
  • 83 + 18287 = 18370
  • 101 + 18269 = 18370
  • 113 + 18257 = 18370

Showing the first eight; more decompositions exist.
