Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404748, here are decompositions:

  • 37 + 2147404711 = 2147404748
  • 109 + 2147404639 = 2147404748
  • 127 + 2147404621 = 2147404748
  • 367 + 2147404381 = 2147404748
  • 421 + 2147404327 = 2147404748
  • 439 + 2147404309 = 2147404748
  • 607 + 2147404141 = 2147404748
  • 859 + 2147403889 = 2147404748

Showing the first eight; more decompositions exist.
