Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469946, here are decompositions:

  • 3 + 2147469943 = 2147469946
  • 29 + 2147469917 = 2147469946
  • 317 + 2147469629 = 2147469946
  • 353 + 2147469593 = 2147469946
  • 599 + 2147469347 = 2147469946
  • 617 + 2147469329 = 2147469946
  • 683 + 2147469263 = 2147469946
  • 773 + 2147469173 = 2147469946

Showing the first eight; more decompositions exist.
