Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147541866, here are decompositions:

  • 13 + 2147541853 = 2147541866
  • 73 + 2147541793 = 2147541866
  • 163 + 2147541703 = 2147541866
  • 229 + 2147541637 = 2147541866
  • 277 + 2147541589 = 2147541866
  • 307 + 2147541559 = 2147541866
  • 397 + 2147541469 = 2147541866
  • 997 + 2147540869 = 2147541866

Showing the first eight; more decompositions exist.
