Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469642, here are decompositions:

  • 5 + 2147469637 = 2147469642
  • 13 + 2147469629 = 2147469642
  • 23 + 2147469619 = 2147469642
  • 89 + 2147469553 = 2147469642
  • 151 + 2147469491 = 2147469642
  • 179 + 2147469463 = 2147469642
  • 193 + 2147469449 = 2147469642
  • 223 + 2147469419 = 2147469642

Showing the first eight; more decompositions exist.
