Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147521934, here are decompositions:

  • 7 + 2147521927 = 2147521934
  • 157 + 2147521777 = 2147521934
  • 211 + 2147521723 = 2147521934
  • 307 + 2147521627 = 2147521934
  • 367 + 2147521567 = 2147521934
  • 433 + 2147521501 = 2147521934
  • 541 + 2147521393 = 2147521934
  • 643 + 2147521291 = 2147521934

Showing the first eight; more decompositions exist.
