Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533394, here are decompositions:

  • 5 + 31533389 = 31533394
  • 23 + 31533371 = 31533394
  • 227 + 31533167 = 31533394
  • 251 + 31533143 = 31533394
  • 293 + 31533101 = 31533394
  • 521 + 31532873 = 31533394
  • 617 + 31532777 = 31533394
  • 701 + 31532693 = 31533394

Showing the first eight; more decompositions exist.
