Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469892, here are decompositions:

  • 11 + 2147469881 = 2147469892
  • 233 + 2147469659 = 2147469892
  • 263 + 2147469629 = 2147469892
  • 401 + 2147469491 = 2147469892
  • 443 + 2147469449 = 2147469892
  • 563 + 2147469329 = 2147469892
  • 653 + 2147469239 = 2147469892
  • 719 + 2147469173 = 2147469892

Showing the first eight; more decompositions exist.
