Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467924, here are decompositions:

  • 3 + 2147467921 = 2147467924
  • 5 + 2147467919 = 2147467924
  • 53 + 2147467871 = 2147467924
  • 131 + 2147467793 = 2147467924
  • 191 + 2147467733 = 2147467924
  • 227 + 2147467697 = 2147467924
  • 257 + 2147467667 = 2147467924
  • 293 + 2147467631 = 2147467924

Showing the first eight; more decompositions exist.
