Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426858, here are decompositions:

  • 37 + 2147426821 = 2147426858
  • 229 + 2147426629 = 2147426858
  • 307 + 2147426551 = 2147426858
  • 331 + 2147426527 = 2147426858
  • 337 + 2147426521 = 2147426858
  • 439 + 2147426419 = 2147426858
  • 457 + 2147426401 = 2147426858
  • 541 + 2147426317 = 2147426858

Showing the first eight; more decompositions exist.
