Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474846, here are decompositions:

  • 17 + 31474829 = 31474846
  • 83 + 31474763 = 31474846
  • 113 + 31474733 = 31474846
  • 173 + 31474673 = 31474846
  • 269 + 31474577 = 31474846
  • 443 + 31474403 = 31474846
  • 449 + 31474397 = 31474846
  • 503 + 31474343 = 31474846

Showing the first eight; more decompositions exist.
