Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487990, here are decompositions:

59 + 2147487931 = 2147487990
83 + 2147487907 = 2147487990
157 + 2147487833 = 2147487990
163 + 2147487827 = 2147487990
173 + 2147487817 = 2147487990
191 + 2147487799 = 2147487990
211 + 2147487779 = 2147487990
233 + 2147487757 = 2147487990

Showing the first eight; more decompositions exist.
