Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528666, here are decompositions:

  • 53 + 31528613 = 31528666
  • 107 + 31528559 = 31528666
  • 167 + 31528499 = 31528666
  • 233 + 31528433 = 31528666
  • 293 + 31528373 = 31528666
  • 317 + 31528349 = 31528666
  • 353 + 31528313 = 31528666
  • 383 + 31528283 = 31528666

Showing the first eight; more decompositions exist.
