Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16000, here are decompositions:

  • 29 + 15971 = 16000
  • 41 + 15959 = 16000
  • 113 + 15887 = 16000
  • 191 + 15809 = 16000
  • 197 + 15803 = 16000
  • 227 + 15773 = 16000
  • 233 + 15767 = 16000
  • 239 + 15761 = 16000

Showing the first eight; more decompositions exist.
