Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489376, here are decompositions:

  • 13 + 31489363 = 31489376
  • 97 + 31489279 = 31489376
  • 199 + 31489177 = 31489376
  • 229 + 31489147 = 31489376
  • 307 + 31489069 = 31489376
  • 313 + 31489063 = 31489376
  • 349 + 31489027 = 31489376
  • 367 + 31489009 = 31489376

Showing the first eight; more decompositions exist.
