Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29680, here are decompositions:

  • 11 + 29669 = 29680
  • 17 + 29663 = 29680
  • 47 + 29633 = 29680
  • 107 + 29573 = 29680
  • 113 + 29567 = 29680
  • 149 + 29531 = 29680
  • 179 + 29501 = 29680
  • 197 + 29483 = 29680

Showing the first eight; more decompositions exist.
