Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499860, here are decompositions:

  • 19 + 2147499841 = 2147499860
  • 31 + 2147499829 = 2147499860
  • 157 + 2147499703 = 2147499860
  • 283 + 2147499577 = 2147499860
  • 313 + 2147499547 = 2147499860
  • 349 + 2147499511 = 2147499860
  • 379 + 2147499481 = 2147499860
  • 409 + 2147499451 = 2147499860

Showing the first eight; more decompositions exist.
