Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518334, here are decompositions:

  • 5 + 31518329 = 31518334
  • 47 + 31518287 = 31518334
  • 53 + 31518281 = 31518334
  • 137 + 31518197 = 31518334
  • 311 + 31518023 = 31518334
  • 383 + 31517951 = 31518334
  • 761 + 31517573 = 31518334
  • 941 + 31517393 = 31518334

Showing the first eight; more decompositions exist.
