Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493138, here are decompositions:

  • 19 + 2147493119 = 2147493138
  • 29 + 2147493109 = 2147493138
  • 59 + 2147493079 = 2147493138
  • 61 + 2147493077 = 2147493138
  • 101 + 2147493037 = 2147493138
  • 137 + 2147493001 = 2147493138
  • 179 + 2147492959 = 2147493138
  • 199 + 2147492939 = 2147493138

Showing the first eight; more decompositions exist.
