Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497508, here are decompositions:

  • 19 + 2147497489 = 2147497508
  • 61 + 2147497447 = 2147497508
  • 97 + 2147497411 = 2147497508
  • 271 + 2147497237 = 2147497508
  • 307 + 2147497201 = 2147497508
  • 367 + 2147497141 = 2147497508
  • 547 + 2147496961 = 2147497508
  • 571 + 2147496937 = 2147497508

Showing the first eight; more decompositions exist.
