Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527018, here are decompositions:

  • 7 + 31527011 = 31527018
  • 79 + 31526939 = 31527018
  • 97 + 31526921 = 31527018
  • 137 + 31526881 = 31527018
  • 139 + 31526879 = 31527018
  • 199 + 31526819 = 31527018
  • 227 + 31526791 = 31527018
  • 241 + 31526777 = 31527018

Showing the first eight; more decompositions exist.
