Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501144, here are decompositions:

  • 13 + 2147501131 = 2147501144
  • 43 + 2147501101 = 2147501144
  • 67 + 2147501077 = 2147501144
  • 157 + 2147500987 = 2147501144
  • 163 + 2147500981 = 2147501144
  • 331 + 2147500813 = 2147501144
  • 421 + 2147500723 = 2147501144
  • 967 + 2147500177 = 2147501144

Showing the first eight; more decompositions exist.
