Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467990, here are decompositions:

  • 23 + 2147467967 = 2147467990
  • 71 + 2147467919 = 2147467990
  • 197 + 2147467793 = 2147467990
  • 257 + 2147467733 = 2147467990
  • 293 + 2147467697 = 2147467990
  • 359 + 2147467631 = 2147467990
  • 431 + 2147467559 = 2147467990
  • 587 + 2147467403 = 2147467990

Showing the first eight; more decompositions exist.
