Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484820, here are decompositions:

  • 29 + 2147484791 = 2147484820
  • 179 + 2147484641 = 2147484820
  • 251 + 2147484569 = 2147484820
  • 293 + 2147484527 = 2147484820
  • 359 + 2147484461 = 2147484820
  • 443 + 2147484377 = 2147484820
  • 587 + 2147484233 = 2147484820
  • 599 + 2147484221 = 2147484820

Showing the first eight; more decompositions exist.
