Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404370, here are decompositions:

  • 43 + 2147404327 = 2147404370
  • 61 + 2147404309 = 2147404370
  • 127 + 2147404243 = 2147404370
  • 229 + 2147404141 = 2147404370
  • 271 + 2147404099 = 2147404370
  • 823 + 2147403547 = 2147404370
  • 967 + 2147403403 = 2147404370
  • 1087 + 2147403283 = 2147404370

Showing the first eight; more decompositions exist.
