Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465902, here are decompositions:

  • 173 + 2147465729 = 2147465902
  • 233 + 2147465669 = 2147465902
  • 293 + 2147465609 = 2147465902
  • 353 + 2147465549 = 2147465902
  • 431 + 2147465471 = 2147465902
  • 479 + 2147465423 = 2147465902
  • 563 + 2147465339 = 2147465902
  • 941 + 2147464961 = 2147465902

Showing the first eight; more decompositions exist.
