Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15756, here are decompositions:

  • 7 + 15749 = 15756
  • 17 + 15739 = 15756
  • 19 + 15737 = 15756
  • 23 + 15733 = 15756
  • 29 + 15727 = 15756
  • 73 + 15683 = 15756
  • 89 + 15667 = 15756
  • 107 + 15649 = 15756

Showing the first eight; more decompositions exist.
