Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18942, here are decompositions:

  • 23 + 18919 = 18942
  • 29 + 18913 = 18942
  • 31 + 18911 = 18942
  • 43 + 18899 = 18942
  • 73 + 18869 = 18942
  • 83 + 18859 = 18942
  • 103 + 18839 = 18942
  • 139 + 18803 = 18942

Showing the first eight; more decompositions exist.
