Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493680, here are decompositions:

19 + 2147493661 = 2147493680
127 + 2147493553 = 2147493680
223 + 2147493457 = 2147493680
271 + 2147493409 = 2147493680
379 + 2147493301 = 2147493680
439 + 2147493241 = 2147493680
571 + 2147493109 = 2147493680
601 + 2147493079 = 2147493680

Showing the first eight; more decompositions exist.
