Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376408, here are decompositions:

  • 7 + 2147376401 = 2147376408
  • 17 + 2147376391 = 2147376408
  • 29 + 2147376379 = 2147376408
  • 31 + 2147376377 = 2147376408
  • 41 + 2147376367 = 2147376408
  • 167 + 2147376241 = 2147376408
  • 257 + 2147376151 = 2147376408
  • 347 + 2147376061 = 2147376408

Showing the first eight; more decompositions exist.
