Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520926, here are decompositions:

  • 29 + 31520897 = 31520926
  • 89 + 31520837 = 31520926
  • 179 + 31520747 = 31520926
  • 347 + 31520579 = 31520926
  • 389 + 31520537 = 31520926
  • 443 + 31520483 = 31520926
  • 509 + 31520417 = 31520926
  • 587 + 31520339 = 31520926

Showing the first eight; more decompositions exist.
