Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483878, here are decompositions:

11 + 2147483867 = 2147483878
101 + 2147483777 = 2147483878
389 + 2147483489 = 2147483878
401 + 2147483477 = 2147483878
479 + 2147483399 = 2147483878
641 + 2147483237 = 2147483878
809 + 2147483069 = 2147483878
929 + 2147482949 = 2147483878

Showing the first eight; more decompositions exist.
