Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147433858, here are decompositions:

  • 47 + 2147433811 = 2147433858
  • 67 + 2147433791 = 2147433858
  • 79 + 2147433779 = 2147433858
  • 139 + 2147433719 = 2147433858
  • 151 + 2147433707 = 2147433858
  • 191 + 2147433667 = 2147433858
  • 281 + 2147433577 = 2147433858
  • 307 + 2147433551 = 2147433858

Showing the first eight; more decompositions exist.
