Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500690, here are decompositions:

  • 29 + 2147500661 = 2147500690
  • 131 + 2147500559 = 2147500690
  • 191 + 2147500499 = 2147500690
  • 197 + 2147500493 = 2147500690
  • 347 + 2147500343 = 2147500690
  • 389 + 2147500301 = 2147500690
  • 431 + 2147500259 = 2147500690
  • 443 + 2147500247 = 2147500690

Showing the first eight; more decompositions exist.
