Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147380924, here are decompositions:

  • 5 + 2147380919 = 2147380924
  • 41 + 2147380883 = 2147380924
  • 71 + 2147380853 = 2147380924
  • 83 + 2147380841 = 2147380924
  • 113 + 2147380811 = 2147380924
  • 137 + 2147380787 = 2147380924
  • 191 + 2147380733 = 2147380924
  • 197 + 2147380727 = 2147380924

Showing the first eight; more decompositions exist.
