Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461344, here are decompositions:

  • 3 + 31461341 = 31461344
  • 43 + 31461301 = 31461344
  • 151 + 31461193 = 31461344
  • 163 + 31461181 = 31461344
  • 181 + 31461163 = 31461344
  • 307 + 31461037 = 31461344
  • 331 + 31461013 = 31461344
  • 337 + 31461007 = 31461344

Showing the first eight; more decompositions exist.
