Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469372, here are decompositions:

  • 43 + 2147469329 = 2147469372
  • 89 + 2147469283 = 2147469372
  • 101 + 2147469271 = 2147469372
  • 109 + 2147469263 = 2147469372
  • 193 + 2147469179 = 2147469372
  • 199 + 2147469173 = 2147469372
  • 239 + 2147469133 = 2147469372
  • 241 + 2147469131 = 2147469372

Showing the first eight; more decompositions exist.
