Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471294, here are decompositions:

  • 5 + 31471289 = 31471294
  • 251 + 31471043 = 31471294
  • 263 + 31471031 = 31471294
  • 293 + 31471001 = 31471294
  • 317 + 31470977 = 31471294
  • 353 + 31470941 = 31471294
  • 383 + 31470911 = 31471294
  • 431 + 31470863 = 31471294

Showing the first eight; more decompositions exist.
