Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147528866, here are decompositions:

  • 5 + 2147528861 = 2147528866
  • 23 + 2147528843 = 2147528866
  • 59 + 2147528807 = 2147528866
  • 89 + 2147528777 = 2147528866
  • 227 + 2147528639 = 2147528866
  • 383 + 2147528483 = 2147528866
  • 467 + 2147528399 = 2147528866
  • 557 + 2147528309 = 2147528866

Showing the first eight; more decompositions exist.
