Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483980, here are decompositions:

29 + 2147483951 = 2147483980
113 + 2147483867 = 2147483980
167 + 2147483813 = 2147483980
197 + 2147483783 = 2147483980
401 + 2147483579 = 2147483980
431 + 2147483549 = 2147483980
491 + 2147483489 = 2147483980
503 + 2147483477 = 2147483980

Showing the first eight; more decompositions exist.
