Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533350, here are decompositions:

  • 7 + 31533343 = 31533350
  • 223 + 31533127 = 31533350
  • 337 + 31533013 = 31533350
  • 349 + 31533001 = 31533350
  • 379 + 31532971 = 31533350
  • 487 + 31532863 = 31533350
  • 601 + 31532749 = 31533350
  • 613 + 31532737 = 31533350

Showing the first eight; more decompositions exist.
