Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483644, here are decompositions:

101 + 2147483543 = 2147483644
167 + 2147483477 = 2147483644
521 + 2147483123 = 2147483644
701 + 2147482943 = 2147483644
827 + 2147482817 = 2147483644
881 + 2147482763 = 2147483644
947 + 2147482697 = 2147483644
983 + 2147482661 = 2147483644

Showing the first eight; more decompositions exist.
