Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51858, here are decompositions:

  • 5 + 51853 = 51858
  • 19 + 51839 = 51858
  • 29 + 51829 = 51858
  • 31 + 51827 = 51858
  • 41 + 51817 = 51858
  • 61 + 51797 = 51858
  • 71 + 51787 = 51858
  • 89 + 51769 = 51858

Showing the first eight; more decompositions exist.
