Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483874, here are decompositions:

  • 5 + 2147483869 = 2147483874
  • 7 + 2147483867 = 2147483874
  • 17 + 2147483857 = 2147483874
  • 61 + 2147483813 = 2147483874
  • 97 + 2147483777 = 2147483874
  • 131 + 2147483743 = 2147483874
  • 181 + 2147483693 = 2147483874
  • 227 + 2147483647 = 2147483874

Showing the first eight; more decompositions exist.
