Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78790, here are decompositions:

  • 3 + 78787 = 78790
  • 11 + 78779 = 78790
  • 53 + 78737 = 78790
  • 83 + 78707 = 78790
  • 137 + 78653 = 78790
  • 167 + 78623 = 78790
  • 197 + 78593 = 78790
  • 251 + 78539 = 78790

Showing the first eight; more decompositions exist.
