Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542284, here are decompositions:

  • 3 + 31542281 = 31542284
  • 181 + 31542103 = 31542284
  • 271 + 31542013 = 31542284
  • 283 + 31542001 = 31542284
  • 307 + 31541977 = 31542284
  • 313 + 31541971 = 31542284
  • 457 + 31541827 = 31542284
  • 523 + 31541761 = 31542284

Showing the first eight; more decompositions exist.
