Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461550, here are decompositions:

  • 17 + 31461533 = 31461550
  • 137 + 31461413 = 31461550
  • 257 + 31461293 = 31461550
  • 269 + 31461281 = 31461550
  • 359 + 31461191 = 31461550
  • 389 + 31461161 = 31461550
  • 401 + 31461149 = 31461550
  • 503 + 31461047 = 31461550

Showing the first eight; more decompositions exist.
