Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526474, here are decompositions:

  • 43 + 31526431 = 31526474
  • 103 + 31526371 = 31526474
  • 157 + 31526317 = 31526474
  • 193 + 31526281 = 31526474
  • 277 + 31526197 = 31526474
  • 283 + 31526191 = 31526474
  • 523 + 31525951 = 31526474
  • 547 + 31525927 = 31526474

Showing the first eight; more decompositions exist.
