Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465386, here are decompositions:

  • 23 + 2147465363 = 2147465386
  • 47 + 2147465339 = 2147465386
  • 173 + 2147465213 = 2147465386
  • 197 + 2147465189 = 2147465386
  • 233 + 2147465153 = 2147465386
  • 797 + 2147464589 = 2147465386
  • 827 + 2147464559 = 2147465386
  • 977 + 2147464409 = 2147465386

Showing the first eight; more decompositions exist.
