Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446474, here are decompositions:

  • 13 + 31446461 = 31446474
  • 47 + 31446427 = 31446474
  • 107 + 31446367 = 31446474
  • 113 + 31446361 = 31446474
  • 151 + 31446323 = 31446474
  • 223 + 31446251 = 31446474
  • 233 + 31446241 = 31446474
  • 251 + 31446223 = 31446474

Showing the first eight; more decompositions exist.
