Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147561762, here are decompositions:

  • 61 + 2147561701 = 2147561762
  • 79 + 2147561683 = 2147561762
  • 193 + 2147561569 = 2147561762
  • 223 + 2147561539 = 2147561762
  • 439 + 2147561323 = 2147561762
  • 571 + 2147561191 = 2147561762
  • 601 + 2147561161 = 2147561762
  • 613 + 2147561149 = 2147561762

Showing the first eight; more decompositions exist.
