Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501178, here are decompositions:

  • 5 + 2147501173 = 2147501178
  • 47 + 2147501131 = 2147501178
  • 89 + 2147501089 = 2147501178
  • 101 + 2147501077 = 2147501178
  • 191 + 2147500987 = 2147501178
  • 197 + 2147500981 = 2147501178
  • 241 + 2147500937 = 2147501178
  • 269 + 2147500909 = 2147501178

Showing the first eight; more decompositions exist.
