Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468428, here are decompositions:

5 + 2147468423 = 2147468428
11 + 2147468417 = 2147468428
137 + 2147468291 = 2147468428
179 + 2147468249 = 2147468428
197 + 2147468231 = 2147468428
239 + 2147468189 = 2147468428
359 + 2147468069 = 2147468428
461 + 2147467967 = 2147468428

Showing the first eight; more decompositions exist.
