Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586450, here are decompositions:

  • 19 + 2147586431 = 2147586450
  • 71 + 2147586379 = 2147586450
  • 89 + 2147586361 = 2147586450
  • 151 + 2147586299 = 2147586450
  • 157 + 2147586293 = 2147586450
  • 173 + 2147586277 = 2147586450
  • 193 + 2147586257 = 2147586450
  • 239 + 2147586211 = 2147586450

Showing the first eight; more decompositions exist.
