Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147389306, here are decompositions:

  • 197 + 2147389109 = 2147389306
  • 239 + 2147389067 = 2147389306
  • 353 + 2147388953 = 2147389306
  • 383 + 2147388923 = 2147389306
  • 743 + 2147388563 = 2147389306
  • 809 + 2147388497 = 2147389306
  • 827 + 2147388479 = 2147389306
  • 929 + 2147388377 = 2147389306

Showing the first eight; more decompositions exist.
