Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27680, here are decompositions:

  • 7 + 27673 = 27680
  • 97 + 27583 = 27680
  • 139 + 27541 = 27680
  • 151 + 27529 = 27680
  • 193 + 27487 = 27680
  • 199 + 27481 = 27680
  • 223 + 27457 = 27680
  • 271 + 27409 = 27680

Showing the first eight; more decompositions exist.
