Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469998, here are decompositions:

  • 181 + 2147469817 = 2147469998
  • 379 + 2147469619 = 2147469998
  • 577 + 2147469421 = 2147469998
  • 727 + 2147469271 = 2147469998
  • 769 + 2147469229 = 2147469998
  • 811 + 2147469187 = 2147469998
  • 991 + 2147469007 = 2147469998
  • 997 + 2147469001 = 2147469998

Showing the first eight; more decompositions exist.
