Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602790, here are decompositions:

  • 101 + 31602689 = 31602790
  • 251 + 31602539 = 31602790
  • 269 + 31602521 = 31602790
  • 293 + 31602497 = 31602790
  • 347 + 31602443 = 31602790
  • 389 + 31602401 = 31602790
  • 467 + 31602323 = 31602790
  • 509 + 31602281 = 31602790

Showing the first eight; more decompositions exist.
