Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472732, here are decompositions:

  • 19 + 2147472713 = 2147472732
  • 43 + 2147472689 = 2147472732
  • 73 + 2147472659 = 2147472732
  • 131 + 2147472601 = 2147472732
  • 233 + 2147472499 = 2147472732
  • 241 + 2147472491 = 2147472732
  • 263 + 2147472469 = 2147472732
  • 283 + 2147472449 = 2147472732

Showing the first eight; more decompositions exist.
