Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473616, here are decompositions:

  • 37 + 2147473579 = 2147473616
  • 139 + 2147473477 = 2147473616
  • 349 + 2147473267 = 2147473616
  • 499 + 2147473117 = 2147473616
  • 733 + 2147472883 = 2147473616
  • 829 + 2147472787 = 2147473616
  • 859 + 2147472757 = 2147473616
  • 919 + 2147472697 = 2147473616

Showing the first eight; more decompositions exist.
