Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483642, here are decompositions:

13 + 2147483629 = 2147483642
79 + 2147483563 = 2147483642
373 + 2147483269 = 2147483642
463 + 2147483179 = 2147483642
613 + 2147483029 = 2147483642
691 + 2147482951 = 2147483642
769 + 2147482873 = 2147483642
823 + 2147482819 = 2147483642

Showing the first eight; more decompositions exist.
