Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500926, here are decompositions:

  • 3 + 31500923 = 31500926
  • 7 + 31500919 = 31500926
  • 73 + 31500853 = 31500926
  • 109 + 31500817 = 31500926
  • 277 + 31500649 = 31500926
  • 337 + 31500589 = 31500926
  • 367 + 31500559 = 31500926
  • 397 + 31500529 = 31500926

Showing the first eight; more decompositions exist.
