Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627000, here are decompositions:

  • 23 + 31626977 = 31627000
  • 101 + 31626899 = 31627000
  • 107 + 31626893 = 31627000
  • 131 + 31626869 = 31627000
  • 173 + 31626827 = 31627000
  • 233 + 31626767 = 31627000
  • 311 + 31626689 = 31627000
  • 443 + 31626557 = 31627000

Showing the first eight; more decompositions exist.
