Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404084, here are decompositions:

  • 17 + 2147404067 = 2147404084
  • 47 + 2147404037 = 2147404084
  • 53 + 2147404031 = 2147404084
  • 83 + 2147404001 = 2147404084
  • 101 + 2147403983 = 2147404084
  • 131 + 2147403953 = 2147404084
  • 191 + 2147403893 = 2147404084
  • 197 + 2147403887 = 2147404084

Showing the first eight; more decompositions exist.
