Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147562866, here are decompositions:

  • 37 + 2147562829 = 2147562866
  • 79 + 2147562787 = 2147562866
  • 223 + 2147562643 = 2147562866
  • 457 + 2147562409 = 2147562866
  • 487 + 2147562379 = 2147562866
  • 499 + 2147562367 = 2147562866
  • 577 + 2147562289 = 2147562866
  • 733 + 2147562133 = 2147562866

Showing the first eight; more decompositions exist.
