Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404372, here are decompositions:

  • 23 + 2147404349 = 2147404372
  • 41 + 2147404331 = 2147404372
  • 53 + 2147404319 = 2147404372
  • 251 + 2147404121 = 2147404372
  • 353 + 2147404019 = 2147404372
  • 389 + 2147403983 = 2147404372
  • 419 + 2147403953 = 2147404372
  • 479 + 2147403893 = 2147404372

Showing the first eight; more decompositions exist.
