Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147567998, here are decompositions:

  • 29 + 2147567969 = 2147567998
  • 131 + 2147567867 = 2147567998
  • 239 + 2147567759 = 2147567998
  • 281 + 2147567717 = 2147567998
  • 347 + 2147567651 = 2147567998
  • 431 + 2147567567 = 2147567998
  • 467 + 2147567531 = 2147567998
  • 491 + 2147567507 = 2147567998

Showing the first eight; more decompositions exist.
