Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497958, here are decompositions:

  • 19 + 2147497939 = 2147497958
  • 37 + 2147497921 = 2147497958
  • 241 + 2147497717 = 2147497958
  • 499 + 2147497459 = 2147497958
  • 547 + 2147497411 = 2147497958
  • 757 + 2147497201 = 2147497958
  • 877 + 2147497081 = 2147497958
  • 919 + 2147497039 = 2147497958

Showing the first eight; more decompositions exist.
