Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497378, here are decompositions:

  • 17 + 2147497361 = 2147497378
  • 29 + 2147497349 = 2147497378
  • 359 + 2147497019 = 2147497378
  • 461 + 2147496917 = 2147497378
  • 599 + 2147496779 = 2147497378
  • 647 + 2147496731 = 2147497378
  • 809 + 2147496569 = 2147497378
  • 821 + 2147496557 = 2147497378

Showing the first eight; more decompositions exist.
