Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528444, here are decompositions:

  • 11 + 31528433 = 31528444
  • 71 + 31528373 = 31528444
  • 107 + 31528337 = 31528444
  • 131 + 31528313 = 31528444
  • 293 + 31528151 = 31528444
  • 317 + 31528127 = 31528444
  • 443 + 31528001 = 31528444
  • 503 + 31527941 = 31528444

Showing the first eight; more decompositions exist.
