Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15876, here are decompositions:

  • 17 + 15859 = 15876
  • 53 + 15823 = 15876
  • 59 + 15817 = 15876
  • 67 + 15809 = 15876
  • 73 + 15803 = 15876
  • 79 + 15797 = 15876
  • 89 + 15787 = 15876
  • 103 + 15773 = 15876

Showing the first eight; more decompositions exist.
