Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38878, here are decompositions:

  • 5 + 38873 = 38878
  • 11 + 38867 = 38878
  • 17 + 38861 = 38878
  • 131 + 38747 = 38878
  • 149 + 38729 = 38878
  • 167 + 38711 = 38878
  • 179 + 38699 = 38878
  • 227 + 38651 = 38878

Showing the first eight; more decompositions exist.
