Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483872, here are decompositions:

  • 3 + 2147483869 = 2147483872
  • 5 + 2147483867 = 2147483872
  • 59 + 2147483813 = 2147483872
  • 89 + 2147483783 = 2147483872
  • 179 + 2147483693 = 2147483872
  • 293 + 2147483579 = 2147483872
  • 383 + 2147483489 = 2147483872
  • 449 + 2147483423 = 2147483872

Showing the first eight; more decompositions exist.
