Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497436, here are decompositions:

  • 43 + 2147497393 = 2147497436
  • 193 + 2147497243 = 2147497436
  • 199 + 2147497237 = 2147497436
  • 397 + 2147497039 = 2147497436
  • 439 + 2147496997 = 2147497436
  • 457 + 2147496979 = 2147497436
  • 499 + 2147496937 = 2147497436
  • 577 + 2147496859 = 2147497436

Showing the first eight; more decompositions exist.
