Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491412, here are decompositions:

43 + 2147491369 = 2147491412
139 + 2147491273 = 2147491412
151 + 2147491261 = 2147491412
163 + 2147491249 = 2147491412
193 + 2147491219 = 2147491412
211 + 2147491201 = 2147491412
331 + 2147491081 = 2147491412
379 + 2147491033 = 2147491412

Showing the first eight; more decompositions exist.
