Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404826, here are decompositions:

  • 337 + 2147404489 = 2147404826
  • 379 + 2147404447 = 2147404826
  • 397 + 2147404429 = 2147404826
  • 433 + 2147404393 = 2147404826
  • 499 + 2147404327 = 2147404826
  • 643 + 2147404183 = 2147404826
  • 673 + 2147404153 = 2147404826
  • 727 + 2147404099 = 2147404826

Showing the first eight; more decompositions exist.
