Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518898, here are decompositions:

  • 5 + 518893 = 518898
  • 31 + 518867 = 518898
  • 67 + 518831 = 518898
  • 89 + 518809 = 518898
  • 97 + 518801 = 518898
  • 131 + 518767 = 518898
  • 137 + 518761 = 518898
  • 139 + 518759 = 518898

Showing the first eight; more decompositions exist.
