Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588860, here are decompositions:

  • 3 + 2147588857 = 2147588860
  • 233 + 2147588627 = 2147588860
  • 239 + 2147588621 = 2147588860
  • 251 + 2147588609 = 2147588860
  • 311 + 2147588549 = 2147588860
  • 317 + 2147588543 = 2147588860
  • 359 + 2147588501 = 2147588860
  • 479 + 2147588381 = 2147588860

Showing the first eight; more decompositions exist.
