Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147529398, here are decompositions:

  • 19 + 2147529379 = 2147529398
  • 37 + 2147529361 = 2147529398
  • 67 + 2147529331 = 2147529398
  • 277 + 2147529121 = 2147529398
  • 349 + 2147529049 = 2147529398
  • 367 + 2147529031 = 2147529398
  • 409 + 2147528989 = 2147529398
  • 439 + 2147528959 = 2147529398

Showing the first eight; more decompositions exist.
