Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469340, here are decompositions:

  • 11 + 2147469329 = 2147469340
  • 101 + 2147469239 = 2147469340
  • 167 + 2147469173 = 2147469340
  • 227 + 2147469113 = 2147469340
  • 239 + 2147469101 = 2147469340
  • 251 + 2147469089 = 2147469340
  • 293 + 2147469047 = 2147469340
  • 347 + 2147468993 = 2147469340

Showing the first eight; more decompositions exist.
