Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429612, here are decompositions:

  • 199 + 2147429413 = 2147429612
  • 331 + 2147429281 = 2147429612
  • 379 + 2147429233 = 2147429612
  • 439 + 2147429173 = 2147429612
  • 541 + 2147429071 = 2147429612
  • 613 + 2147428999 = 2147429612
  • 631 + 2147428981 = 2147429612
  • 751 + 2147428861 = 2147429612

Showing the first eight; more decompositions exist.
