Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588370, here are decompositions:

17 + 2147588353 = 2147588370
29 + 2147588341 = 2147588370
61 + 2147588309 = 2147588370
89 + 2147588281 = 2147588370
107 + 2147588263 = 2147588370
131 + 2147588239 = 2147588370
167 + 2147588203 = 2147588370
173 + 2147588197 = 2147588370

Showing the first eight; more decompositions exist.
