Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497338, here are decompositions:

  • 17 + 2147497321 = 2147497338
  • 101 + 2147497237 = 2147497338
  • 137 + 2147497201 = 2147497338
  • 197 + 2147497141 = 2147497338
  • 257 + 2147497081 = 2147497338
  • 359 + 2147496979 = 2147497338
  • 367 + 2147496971 = 2147497338
  • 397 + 2147496941 = 2147497338

Showing the first eight; more decompositions exist.
