Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487970, here are decompositions:

29 + 2147487941 = 2147487970
71 + 2147487899 = 2147487970
101 + 2147487869 = 2147487970
137 + 2147487833 = 2147487970
167 + 2147487803 = 2147487970
191 + 2147487779 = 2147487970
197 + 2147487773 = 2147487970
269 + 2147487701 = 2147487970

Showing the first eight; more decompositions exist.
