Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497562, here are decompositions:

  • 3 + 2147497559 = 2147497562
  • 73 + 2147497489 = 2147497562
  • 103 + 2147497459 = 2147497562
  • 151 + 2147497411 = 2147497562
  • 241 + 2147497321 = 2147497562
  • 421 + 2147497141 = 2147497562
  • 523 + 2147497039 = 2147497562
  • 601 + 2147496961 = 2147497562

Showing the first eight; more decompositions exist.
