Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491518, here are decompositions:

  • 41 + 2147491477 = 2147491518
  • 101 + 2147491417 = 2147491518
  • 149 + 2147491369 = 2147491518
  • 157 + 2147491361 = 2147491518
  • 199 + 2147491319 = 2147491518
  • 241 + 2147491277 = 2147491518
  • 257 + 2147491261 = 2147491518
  • 269 + 2147491249 = 2147491518

Showing the first eight; more decompositions exist.
