Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15760, here are decompositions:

  • 11 + 15749 = 15760
  • 23 + 15737 = 15760
  • 29 + 15731 = 15760
  • 89 + 15671 = 15760
  • 113 + 15647 = 15760
  • 131 + 15629 = 15760
  • 179 + 15581 = 15760
  • 191 + 15569 = 15760

Showing the first eight; more decompositions exist.
