Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443100, here are decompositions:

  • 13 + 2147443087 = 2147443100
  • 43 + 2147443057 = 2147443100
  • 67 + 2147443033 = 2147443100
  • 79 + 2147443021 = 2147443100
  • 97 + 2147443003 = 2147443100
  • 139 + 2147442961 = 2147443100
  • 199 + 2147442901 = 2147443100
  • 277 + 2147442823 = 2147443100

Showing the first eight; more decompositions exist.
