Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443098, here are decompositions:

  • 11 + 2147443087 = 2147443098
  • 41 + 2147443057 = 2147443098
  • 109 + 2147442989 = 2147443098
  • 137 + 2147442961 = 2147443098
  • 167 + 2147442931 = 2147443098
  • 197 + 2147442901 = 2147443098
  • 271 + 2147442827 = 2147443098
  • 331 + 2147442767 = 2147443098

Showing the first eight; more decompositions exist.
