Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483842, here are decompositions:

29 + 2147483813 = 2147483842
59 + 2147483783 = 2147483842
149 + 2147483693 = 2147483842
263 + 2147483579 = 2147483842
293 + 2147483549 = 2147483842
353 + 2147483489 = 2147483842
419 + 2147483423 = 2147483842
443 + 2147483399 = 2147483842

Showing the first eight; more decompositions exist.
