Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404408, here are decompositions:

  • 59 + 2147404349 = 2147404408
  • 89 + 2147404319 = 2147404408
  • 179 + 2147404229 = 2147404408
  • 197 + 2147404211 = 2147404408
  • 251 + 2147404157 = 2147404408
  • 389 + 2147404019 = 2147404408
  • 521 + 2147403887 = 2147404408
  • 827 + 2147403581 = 2147404408

Showing the first eight; more decompositions exist.
