Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467544, here are decompositions:

  • 73 + 2147467471 = 2147467544
  • 151 + 2147467393 = 2147467544
  • 223 + 2147467321 = 2147467544
  • 283 + 2147467261 = 2147467544
  • 487 + 2147467057 = 2147467544
  • 571 + 2147466973 = 2147467544
  • 601 + 2147466943 = 2147467544
  • 613 + 2147466931 = 2147467544

Showing the first eight; more decompositions exist.
