Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497674, here are decompositions:

  • 11 + 2147497663 = 2147497674
  • 13 + 2147497661 = 2147497674
  • 103 + 2147497571 = 2147497674
  • 151 + 2147497523 = 2147497674
  • 167 + 2147497507 = 2147497674
  • 181 + 2147497493 = 2147497674
  • 193 + 2147497481 = 2147497674
  • 227 + 2147497447 = 2147497674

Showing the first eight; more decompositions exist.
