Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473788, here are decompositions:

  • 7 + 2147473781 = 2147473788
  • 311 + 2147473477 = 2147473788
  • 359 + 2147473429 = 2147473788
  • 379 + 2147473409 = 2147473788
  • 419 + 2147473369 = 2147473788
  • 457 + 2147473331 = 2147473788
  • 487 + 2147473301 = 2147473788
  • 491 + 2147473297 = 2147473788

Showing the first eight; more decompositions exist.
