Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469994, here are decompositions:

  • 11 + 2147469983 = 2147469994
  • 113 + 2147469881 = 2147469994
  • 401 + 2147469593 = 2147469994
  • 503 + 2147469491 = 2147469994
  • 647 + 2147469347 = 2147469994
  • 821 + 2147469173 = 2147469994
  • 863 + 2147469131 = 2147469994
  • 881 + 2147469113 = 2147469994

Showing the first eight; more decompositions exist.
