Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491582, here are decompositions:

23 + 2147491559 = 2147491582
29 + 2147491553 = 2147491582
179 + 2147491403 = 2147491582
233 + 2147491349 = 2147491582
239 + 2147491343 = 2147491582
263 + 2147491319 = 2147491582
359 + 2147491223 = 2147491582
389 + 2147491193 = 2147491582

Showing the first eight; more decompositions exist.
