Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497340, here are decompositions:

  • 19 + 2147497321 = 2147497340
  • 97 + 2147497243 = 2147497340
  • 103 + 2147497237 = 2147497340
  • 139 + 2147497201 = 2147497340
  • 199 + 2147497141 = 2147497340
  • 379 + 2147496961 = 2147497340
  • 487 + 2147496853 = 2147497340
  • 523 + 2147496817 = 2147497340

Showing the first eight; more decompositions exist.
