Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472436, here are decompositions:

  • 23 + 2147472413 = 2147472436
  • 59 + 2147472377 = 2147472436
  • 173 + 2147472263 = 2147472436
  • 293 + 2147472143 = 2147472436
  • 383 + 2147472053 = 2147472436
  • 443 + 2147471993 = 2147472436
  • 503 + 2147471933 = 2147472436
  • 677 + 2147471759 = 2147472436

Showing the first eight; more decompositions exist.
