Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483788, here are decompositions:

5 + 2147483783 = 2147483788
11 + 2147483777 = 2147483788
239 + 2147483549 = 2147483788
311 + 2147483477 = 2147483788
389 + 2147483399 = 2147483788
617 + 2147483171 = 2147483788
719 + 2147483069 = 2147483788
839 + 2147482949 = 2147483788

Showing the first eight; more decompositions exist.
