Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500566, here are decompositions:

  • 5 + 2147500561 = 2147500566
  • 7 + 2147500559 = 2147500566
  • 59 + 2147500507 = 2147500566
  • 67 + 2147500499 = 2147500566
  • 73 + 2147500493 = 2147500566
  • 223 + 2147500343 = 2147500566
  • 227 + 2147500339 = 2147500566
  • 269 + 2147500297 = 2147500566

Showing the first eight; more decompositions exist.
