Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426992, here are decompositions:

  • 3 + 2147426989 = 2147426992
  • 41 + 2147426951 = 2147426992
  • 149 + 2147426843 = 2147426992
  • 311 + 2147426681 = 2147426992
  • 419 + 2147426573 = 2147426992
  • 449 + 2147426543 = 2147426992
  • 521 + 2147426471 = 2147426992
  • 593 + 2147426399 = 2147426992

Showing the first eight; more decompositions exist.
