Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467438, here are decompositions:

  • 59 + 2147467379 = 2147467438
  • 71 + 2147467367 = 2147467438
  • 107 + 2147467331 = 2147467438
  • 227 + 2147467211 = 2147467438
  • 269 + 2147467169 = 2147467438
  • 317 + 2147467121 = 2147467438
  • 491 + 2147466947 = 2147467438
  • 569 + 2147466869 = 2147467438

Showing the first eight; more decompositions exist.
