Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497752, here are decompositions:

  • 19 + 2147497733 = 2147497752
  • 53 + 2147497699 = 2147497752
  • 61 + 2147497691 = 2147497752
  • 89 + 2147497663 = 2147497752
  • 181 + 2147497571 = 2147497752
  • 193 + 2147497559 = 2147497752
  • 229 + 2147497523 = 2147497752
  • 263 + 2147497489 = 2147497752

Showing the first eight; more decompositions exist.
