Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469288, here are decompositions:

  • 5 + 2147469283 = 2147469288
  • 17 + 2147469271 = 2147469288
  • 59 + 2147469229 = 2147469288
  • 101 + 2147469187 = 2147469288
  • 109 + 2147469179 = 2147469288
  • 131 + 2147469157 = 2147469288
  • 157 + 2147469131 = 2147469288
  • 199 + 2147469089 = 2147469288

Showing the first eight; more decompositions exist.
