Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487718, here are decompositions:

17 + 2147487701 = 2147487718
29 + 2147487689 = 2147487718
107 + 2147487611 = 2147487718
269 + 2147487449 = 2147487718
317 + 2147487401 = 2147487718
359 + 2147487359 = 2147487718
449 + 2147487269 = 2147487718
491 + 2147487227 = 2147487718

Showing the first eight; more decompositions exist.
