Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483938, here are decompositions:

71 + 2147483867 = 2147483938
359 + 2147483579 = 2147483938
389 + 2147483549 = 2147483938
449 + 2147483489 = 2147483938
461 + 2147483477 = 2147483938
701 + 2147483237 = 2147483938
1061 + 2147482877 = 2147483938
1277 + 2147482661 = 2147483938

Showing the first eight; more decompositions exist.
