Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571680, here are decompositions:

7 + 571673 = 571680
23 + 571657 = 571680
47 + 571633 = 571680
79 + 571601 = 571680
97 + 571583 = 571680
101 + 571579 = 571680
139 + 571541 = 571680
149 + 571531 = 571680

Showing the first eight; more decompositions exist.
