Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491166, here are decompositions:

  • 43 + 2147491123 = 2147491166
  • 97 + 2147491069 = 2147491166
  • 193 + 2147490973 = 2147491166
  • 199 + 2147490967 = 2147491166
  • 283 + 2147490883 = 2147491166
  • 367 + 2147490799 = 2147491166
  • 397 + 2147490769 = 2147491166
  • 439 + 2147490727 = 2147491166

Showing the first eight; more decompositions exist.
