Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528012, here are decompositions:

  • 11 + 31528001 = 31528012
  • 71 + 31527941 = 31528012
  • 311 + 31527701 = 31528012
  • 353 + 31527659 = 31528012
  • 443 + 31527569 = 31528012
  • 479 + 31527533 = 31528012
  • 491 + 31527521 = 31528012
  • 521 + 31527491 = 31528012

Showing the first eight; more decompositions exist.
