Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404394, here are decompositions:

  • 13 + 2147404381 = 2147404394
  • 67 + 2147404327 = 2147404394
  • 151 + 2147404243 = 2147404394
  • 211 + 2147404183 = 2147404394
  • 241 + 2147404153 = 2147404394
  • 613 + 2147403781 = 2147404394
  • 937 + 2147403457 = 2147404394
  • 991 + 2147403403 = 2147404394

Showing the first eight; more decompositions exist.
