Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571720, here are decompositions:

3 + 571717 = 571720
11 + 571709 = 571720
41 + 571679 = 571720
47 + 571673 = 571720
131 + 571589 = 571720
137 + 571583 = 571720
179 + 571541 = 571720
311 + 571409 = 571720

Showing the first eight; more decompositions exist.
