Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78782, here are decompositions:

  • 3 + 78779 = 78782
  • 61 + 78721 = 78782
  • 139 + 78643 = 78782
  • 199 + 78583 = 78782
  • 211 + 78571 = 78782
  • 229 + 78553 = 78782
  • 241 + 78541 = 78782
  • 271 + 78511 = 78782

Showing the first eight; more decompositions exist.
