Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485770, here are decompositions:

  • 11 + 2147485759 = 2147485770
  • 83 + 2147485687 = 2147485770
  • 97 + 2147485673 = 2147485770
  • 179 + 2147485591 = 2147485770
  • 197 + 2147485573 = 2147485770
  • 211 + 2147485559 = 2147485770
  • 223 + 2147485547 = 2147485770
  • 271 + 2147485499 = 2147485770

Showing the first eight; more decompositions exist.
