Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404838, here are decompositions:

  • 67 + 2147404771 = 2147404838
  • 127 + 2147404711 = 2147404838
  • 199 + 2147404639 = 2147404838
  • 349 + 2147404489 = 2147404838
  • 409 + 2147404429 = 2147404838
  • 457 + 2147404381 = 2147404838
  • 739 + 2147404099 = 2147404838
  • 1291 + 2147403547 = 2147404838

Showing the first eight; more decompositions exist.
