Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483890, here are decompositions:

3 + 2147483887 = 2147483890
23 + 2147483867 = 2147483890
107 + 2147483783 = 2147483890
113 + 2147483777 = 2147483890
197 + 2147483693 = 2147483890
311 + 2147483579 = 2147483890
347 + 2147483543 = 2147483890
401 + 2147483489 = 2147483890

Showing the first eight; more decompositions exist.
