Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469194, here are decompositions:

  • 7 + 2147469187 = 2147469194
  • 37 + 2147469157 = 2147469194
  • 61 + 2147469133 = 2147469194
  • 127 + 2147469067 = 2147469194
  • 193 + 2147469001 = 2147469194
  • 223 + 2147468971 = 2147469194
  • 271 + 2147468923 = 2147469194
  • 307 + 2147468887 = 2147469194

Showing the first eight; more decompositions exist.
