Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474028, here are decompositions:

  • 37 + 31473991 = 31474028
  • 97 + 31473931 = 31474028
  • 127 + 31473901 = 31474028
  • 181 + 31473847 = 31474028
  • 499 + 31473529 = 31474028
  • 541 + 31473487 = 31474028
  • 571 + 31473457 = 31474028
  • 631 + 31473397 = 31474028

Showing the first eight; more decompositions exist.
