Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491446, here are decompositions:

29 + 2147491417 = 2147491446
43 + 2147491403 = 2147491446
97 + 2147491349 = 2147491446
103 + 2147491343 = 2147491446
127 + 2147491319 = 2147491446
173 + 2147491273 = 2147491446
197 + 2147491249 = 2147491446
223 + 2147491223 = 2147491446

Showing the first eight; more decompositions exist.
