Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465404, here are decompositions:

  • 13 + 31465391 = 31465404
  • 41 + 31465363 = 31465404
  • 83 + 31465321 = 31465404
  • 181 + 31465223 = 31465404
  • 211 + 31465193 = 31465404
  • 227 + 31465177 = 31465404
  • 251 + 31465153 = 31465404
  • 281 + 31465123 = 31465404

Showing the first eight; more decompositions exist.
