Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474312, here are decompositions:

  • 5 + 31474307 = 31474312
  • 11 + 31474301 = 31474312
  • 59 + 31474253 = 31474312
  • 239 + 31474073 = 31474312
  • 251 + 31474061 = 31474312
  • 269 + 31474043 = 31474312
  • 449 + 31473863 = 31474312
  • 503 + 31473809 = 31474312

Showing the first eight; more decompositions exist.
