Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78990, here are decompositions:

  • 11 + 78979 = 78990
  • 13 + 78977 = 78990
  • 61 + 78929 = 78990
  • 71 + 78919 = 78990
  • 89 + 78901 = 78990
  • 97 + 78893 = 78990
  • 101 + 78889 = 78990
  • 103 + 78887 = 78990

Showing the first eight; more decompositions exist.
