Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461284, here are decompositions:

  • 3 + 31461281 = 31461284
  • 31 + 31461253 = 31461284
  • 61 + 31461223 = 31461284
  • 103 + 31461181 = 31461284
  • 157 + 31461127 = 31461284
  • 271 + 31461013 = 31461284
  • 277 + 31461007 = 31461284
  • 307 + 31460977 = 31461284

Showing the first eight; more decompositions exist.
