Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467578, here are decompositions:

  • 19 + 2147467559 = 2147467578
  • 107 + 2147467471 = 2147467578
  • 199 + 2147467379 = 2147467578
  • 211 + 2147467367 = 2147467578
  • 239 + 2147467339 = 2147467578
  • 251 + 2147467327 = 2147467578
  • 257 + 2147467321 = 2147467578
  • 317 + 2147467261 = 2147467578

Showing the first eight; more decompositions exist.
