Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467388, here are decompositions:

  • 61 + 2147467327 = 2147467388
  • 67 + 2147467321 = 2147467388
  • 127 + 2147467261 = 2147467388
  • 331 + 2147467057 = 2147467388
  • 379 + 2147467009 = 2147467388
  • 397 + 2147466991 = 2147467388
  • 457 + 2147466931 = 2147467388
  • 541 + 2147466847 = 2147467388

Showing the first eight; more decompositions exist.
