Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485204, here are decompositions:

  • 7 + 31485197 = 31485204
  • 11 + 31485193 = 31485204
  • 13 + 31485191 = 31485204
  • 83 + 31485121 = 31485204
  • 97 + 31485107 = 31485204
  • 103 + 31485101 = 31485204
  • 137 + 31485067 = 31485204
  • 173 + 31485031 = 31485204

Showing the first eight; more decompositions exist.
