Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472532, here are decompositions:

  • 41 + 2147472491 = 2147472532
  • 83 + 2147472449 = 2147472532
  • 89 + 2147472443 = 2147472532
  • 269 + 2147472263 = 2147472532
  • 281 + 2147472251 = 2147472532
  • 311 + 2147472221 = 2147472532
  • 389 + 2147472143 = 2147472532
  • 431 + 2147472101 = 2147472532

Showing the first eight; more decompositions exist.
