Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85878, here are decompositions:

  • 31 + 85847 = 85878
  • 41 + 85837 = 85878
  • 47 + 85831 = 85878
  • 59 + 85819 = 85878
  • 61 + 85817 = 85878
  • 97 + 85781 = 85878
  • 127 + 85751 = 85878
  • 167 + 85711 = 85878

Showing the first eight; more decompositions exist.
