Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491862, here are decompositions:

31 + 2147491831 = 2147491862
163 + 2147491699 = 2147491862
601 + 2147491261 = 2147491862
613 + 2147491249 = 2147491862
643 + 2147491219 = 2147491862
661 + 2147491201 = 2147491862
739 + 2147491123 = 2147491862
751 + 2147491111 = 2147491862

Showing the first eight; more decompositions exist.
