Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404734, here are decompositions:

  • 23 + 2147404711 = 2147404734
  • 113 + 2147404621 = 2147404734
  • 151 + 2147404583 = 2147404734
  • 157 + 2147404577 = 2147404734
  • 353 + 2147404381 = 2147404734
  • 487 + 2147404247 = 2147404734
  • 491 + 2147404243 = 2147404734
  • 523 + 2147404211 = 2147404734

Showing the first eight; more decompositions exist.
