Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147433892, here are decompositions:

  • 5 + 2147433887 = 2147433892
  • 101 + 2147433791 = 2147433892
  • 113 + 2147433779 = 2147433892
  • 173 + 2147433719 = 2147433892
  • 389 + 2147433503 = 2147433892
  • 491 + 2147433401 = 2147433892
  • 503 + 2147433389 = 2147433892
  • 719 + 2147433173 = 2147433892

Showing the first eight; more decompositions exist.
