Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503496, here are decompositions:

  • 53 + 31503443 = 31503496
  • 173 + 31503323 = 31503496
  • 293 + 31503203 = 31503496
  • 317 + 31503179 = 31503496
  • 389 + 31503107 = 31503496
  • 443 + 31503053 = 31503496
  • 503 + 31502993 = 31503496
  • 569 + 31502927 = 31503496

Showing the first eight; more decompositions exist.
