Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63878, here are decompositions:

  • 37 + 63841 = 63878
  • 79 + 63799 = 63878
  • 97 + 63781 = 63878
  • 151 + 63727 = 63878
  • 181 + 63697 = 63878
  • 211 + 63667 = 63878
  • 229 + 63649 = 63878
  • 271 + 63607 = 63878

Showing the first eight; more decompositions exist.
