Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497146, here are decompositions:

  • 5 + 2147497141 = 2147497146
  • 13 + 2147497133 = 2147497146
  • 103 + 2147497043 = 2147497146
  • 107 + 2147497039 = 2147497146
  • 127 + 2147497019 = 2147497146
  • 149 + 2147496997 = 2147497146
  • 167 + 2147496979 = 2147497146
  • 229 + 2147496917 = 2147497146

Showing the first eight; more decompositions exist.
