Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497564, here are decompositions:

  • 5 + 2147497559 = 2147497564
  • 41 + 2147497523 = 2147497564
  • 71 + 2147497493 = 2147497564
  • 83 + 2147497481 = 2147497564
  • 431 + 2147497133 = 2147497564
  • 521 + 2147497043 = 2147497564
  • 593 + 2147496971 = 2147497564
  • 647 + 2147496917 = 2147497564

Showing the first eight; more decompositions exist.
