Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571572, here are decompositions:

31 + 571541 = 571572
41 + 571531 = 571572
101 + 571471 = 571572
139 + 571433 = 571572
163 + 571409 = 571572
173 + 571399 = 571572
191 + 571381 = 571572
233 + 571339 = 571572

Showing the first eight; more decompositions exist.
