Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469538, here are decompositions:

  • 17 + 2147469521 = 2147469538
  • 47 + 2147469491 = 2147469538
  • 89 + 2147469449 = 2147469538
  • 191 + 2147469347 = 2147469538
  • 359 + 2147469179 = 2147469538
  • 449 + 2147469089 = 2147469538
  • 491 + 2147469047 = 2147469538
  • 521 + 2147469017 = 2147469538

Showing the first eight; more decompositions exist.
