Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477930, here are decompositions:

  • 79 + 2147477851 = 2147477930
  • 97 + 2147477833 = 2147477930
  • 193 + 2147477737 = 2147477930
  • 229 + 2147477701 = 2147477930
  • 331 + 2147477599 = 2147477930
  • 397 + 2147477533 = 2147477930
  • 457 + 2147477473 = 2147477930
  • 463 + 2147477467 = 2147477930

Showing the first eight; more decompositions exist.
