Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443748, here are decompositions:

  • 19 + 2147443729 = 2147443748
  • 181 + 2147443567 = 2147443748
  • 211 + 2147443537 = 2147443748
  • 277 + 2147443471 = 2147443748
  • 337 + 2147443411 = 2147443748
  • 349 + 2147443399 = 2147443748
  • 409 + 2147443339 = 2147443748
  • 577 + 2147443171 = 2147443748

Showing the first eight; more decompositions exist.
