Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497552, here are decompositions:

  • 29 + 2147497523 = 2147497552
  • 59 + 2147497493 = 2147497552
  • 71 + 2147497481 = 2147497552
  • 149 + 2147497403 = 2147497552
  • 191 + 2147497361 = 2147497552
  • 419 + 2147497133 = 2147497552
  • 509 + 2147497043 = 2147497552
  • 773 + 2147496779 = 2147497552

Showing the first eight; more decompositions exist.
