Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435470, here are decompositions:

  • 53 + 2147435417 = 2147435470
  • 149 + 2147435321 = 2147435470
  • 227 + 2147435243 = 2147435470
  • 269 + 2147435201 = 2147435470
  • 431 + 2147435039 = 2147435470
  • 461 + 2147435009 = 2147435470
  • 491 + 2147434979 = 2147435470
  • 563 + 2147434907 = 2147435470

Showing the first eight; more decompositions exist.
