Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586518, here are decompositions:

  • 61 + 2147586457 = 2147586518
  • 139 + 2147586379 = 2147586518
  • 157 + 2147586361 = 2147586518
  • 241 + 2147586277 = 2147586518
  • 307 + 2147586211 = 2147586518
  • 331 + 2147586187 = 2147586518
  • 367 + 2147586151 = 2147586518
  • 397 + 2147586121 = 2147586518

Showing the first eight; more decompositions exist.
